I wish all videos were this direct and to the point. Great job
I love how succinct your videos are. Ain’t nobody got time for long videos. Thank you ❤
Short and to the point! Thank you again for the informative video!
Hey MD just mentioned you and your pond soil method. Keep up the good work.
Fascinating! Some excellent stuff in this video - great work
I always appreciate your videos!! Great content and presentation! Bonus is your beautiful tanks! Thanks man! Keep um comin!!
Thx - this is direct and straight to the point.
great video!!
Informativ. Great content😊
Thanks for the helpful information.
Thanks for the good tips 👍🏼👍🏼
Like your approach, very understandable therefore interesting. Thanks
Sharing my experience with BBA..
Strong flow makes hard plants or rounded leaf shape plants (Like Anubias) get BBA. some plants actually like strong flow (maybe the soft narrow leaf type, not sure).
Also noticed water hardness also promotes BBA. When i switched to using mostly rain water (RO/Filtered water), i get less BBA and other Algae issues.
Vallis loves flow, with you on that, and when a large bunch is being pushed horizontal by flow, if water is low in organic waste, no BBA.
Water hardness I am not at all sure about, I have more or less, stopped reducing my water hardness and no increase in BBA. But with softer water CO2 goes further so that might be an indirect affect. Rain water is great to top a tank up with as long as it doesn't come from a roof where pigeon poop is plentiful. Full of Phosphate, keep Phosphate in the substrate not the water column (clay in the substrate is your friend, it binds Phosphate but it remains available for the roots to take it up). Pigeon poop is like guano from sea birds and bats, fierce fertiliser.
No CO2 and hardwater you need strong lights on a short day, you get biogenic decalcification (but the plants need intense light for energy - a long day and low light gives the advantage to algae, including BBA), Swords, Vallis, Hornwort and some Crypts love these conditions, but that means the water is being softened by the plants so don't top-up with rainwater or RO, change the water for tap water or even add baking soda. Who said keeping plants in a fishtank is simple! Thanks for the post, you got me thinking.
I have BBA on one part of a piece of wood and no where else. I also follow 24hraquarist and I’m thinking the reason I have it only here is that the section of wood is right were my fish tend to hang out and also where I feed them. So yeah, excess organic waste. Good job with this. You always help me so much.
thank you so much this helped so much, my go too youtuber.
Thx that's exactly the video I needed
Nice explanation
Thanks MJ!
Very helpfull, thank you. Had bad bba in 450l, thankfully got rid of it by water changes and good maintenance.
The big shallow is looking awesome mate, love the emerged plants.
Sometimes, BBA just pops out from nowhere even when we maintain the best condition for our tanks. That's so annoying.
Great overview. Nice to see your cat too ))
Flow definitely promotes it. I'm sure of that.
I have a growth of BBA on some wood which is in a fairly strong flow area... but the difference is... I've let it grow!
It looks great now: the way it waves about in the flow!
It isn't spreading, which is good. I'm guessing that this patch is healthy and gobbling up nutrients - stunting growth elsewhere? Whatever the reason... I am loving the look of it.
Nice!
Can you make a video about good practices when feeding fishes and shrimps? Thank you for sharing your wisdom
I have just started getting BBA on a piece of wood just below my filter inlet so flow is definitely a contributer. Turning flow and light down now. I also have a light stubble on my plants but I have been holding out on water changes because I read that sometimes adding fresh minerals with water changes feeds the BBA. My water is quite hard. I might try more regular water changes now and see if that solves the plant BBA.
Helpful video. Thanks dear..
Take love from Bangladesh 🇧🇩
You absolutely can get BBA from your local fish store. I've maintained a 120gallon Discus tank for 3 years without BBA. Bought some Tetras from a local fish store that had BBA covered tanks. During the transfer process some BBA entered my tank and spread like wild fire. Because my tank is also planted (anubias, javafern) I basically had to remove all the fish and plants and chlorinated the tank to kill all BBA on all substrate. Then reintroduced the fish. Had to trim all the plants also. I tried low light, and flourish Excell and even hydrogen peroxide. But once BBA invades there is almost no stopping it. It must be removed immediately before it overtakes the tank. (Yes I have another tanks for the discus to live until the tank cycled)
Absolutely gorgeous bowl setup. Does the pea puffer go after the shrimp?
Thanks
Thanks for sharing Mark. My light has a nice night effect that can be turned on. When I do use this effect, the blue light spectrum runs on all day and then few hours in the evening once white and red go off. Excess of blue light spectrum is what caused BBA for me. Sadly, I can't just turn on blue light only in the evening as my light does not have this option so turned it off. I then treated the tank with liquid carbon, BBA turned white and was eaten by fish/dissapeared.
I've never had it until recently when I disturbed my substrate quite a lot to fix the sand the corys had moved over a few months. It obviously releases a lot of nutrients and stuff quite quickly and caused a bloom.
I had the same experience before. Sucking the substrate is so sensitive for me to do now.
Hey I'll keep my comment in English I'm dutch but live in the states. If you use seachem excel or any liquid carbon. Be extremely careful overdosing will be harmful to fish even the recommended dose can be fatal to some vertebrates. Best approach to battle black beard algae is use a seringe with a 18 gauge needle, shut off pump for 10-15 minutes. Inject liquid carbon or excel directly onto the bba just slowly squirt it over it even under water. Leave it for 10 minutes turn your pump and filter back on and it will die off. If you have a lot of bba work in sections every 5 days you do a bit make sure you do a water change 1-2 days after dosing. As always enjoy the hobby and keep it healthy 💖
New subscriber here.
BBA It is very well temperature dependent, can't grow over 27 degrees Celsius. This is why people usually have issues with it in the winter. Even if the tank have heater the heat is not very well distributed and there are colder spots and streams usually where the flow is also higher.
100% it's all about balance, I got bba in one of my set ups and the only way I could remove it was with peroxide, it broke it down enough for the shrimp to make a meal of it.
The 2hr aquarist philosophy is the way to go. Focus on plant health and everything else will fall into place.
Wow just wow ❤❤❤ i miss so much my shrimps tanks but Living on a sailboat make it impossible
Supergaaf filmpje MJ. Er zijn zeker algen die je kunt krijgen via overdracht van sporen. Denk bijvoorbeeld aan blauwalg, vaak worden deze sporen in het water getransporteerd of wanneer je planten koopt die niet invitro gekweekt zijn. Echter is het aankopen van invitro planten niet altijd een garantie dat er geen algen sporen in het water komen. Het meest duidelijke voorbeeld hiervan is wanneer je in de zomer een zwembad vult met kraanwater en deze 2 weken in de brandende zon laat staan. De kans dat dit water groen word van zweefalgen is bijna 100%. Kortom er zijn wel degelijk sporen besmetting mogelijk. Feit is wanneer er een sterke plantgoei tegenover staat de kans op de ontwikkeling van deze algen klein is.
Hey Maarten, cross contamination is in veel gevallen mogelijk Zelfs door lucht verspreiding. Met in vitro planten spelt er nog iets anders. Hier is de kans heel Klein. Waarom? Omdat het vocht in de invitro planten in gel is en daardoor niet een vloeibaar iets is. Daarnaast alle planten die in vitro worden verkocht zijn 9 van de 10 keer gekoeld wat de overdracht en groei afremt
@@aspinwallfamilyhomestead7018 mee eens maar wat ik bedoel is dat wanneer je invitro koopt er nog meerdere factoren zijn waardoor je nog steeds algen kunt krijgen.
Thanks, my new aquascape has got some BBA and hair algae
I'm sure you will get rid of it!
from my recent experience battling with BBA (wont claim victory yet but def getting there): high phosphate levels, or imbalance to be precise, prob induced by too much waste organics as cited in the vid. Tho i kept my tank clean, it is a bit over stocked and i prob over feed a bit too.
Phosphates test isnt included with basic test kits or strips so didnt think my water parameters were off (nitrite/nitrate/amonia at 0). I came across a youtuber mentionning phosphate levels needing to be around 1/10th of nitrates levels to have a good balance for plants. Realizing something isnt adding up here since 1/10th of 0 is 0 in my case so i should prob investigate and buy the test kit.
Turns out my tank was about 1.5-2 ppm phosphate, city water is around .7 to start with... i should have 20ppm nitrates to have that balance the guy was talking about... not fish safe level by most standards.
Bought phosphate scrubbers, popped a tiny piece in the hob. 24h later almost all bba starts turning red, even more dramaticaly than peroxide or excel spot treatment.
After 2 weeks with the scrubber and reducing food portions, PO4 levels are around 0.5 ppm, nitrates levels are slowly going up (not at 5 as it ''should be'' but im at least getting a reading now), i have been able to increase back light power and period (i had shortened the period and put some tape on some leds thinking that was the issue), BBA is almost completly gone and receeding. Still might make another peroxyde spot treatment but i think the balance is slowly settling in.
I had to nearly double the bubble count on the CO2 to get to the same level as before. Plants are looking great. Im guessing the high phosphates levels were favorising bba which consumed everyting exept CO2 leaving the plants starving and unable to take in anything really.
So phosphate levels, check them. Most youtubers and ''experts'' talk about overfeeding and bad maintenance but sometimes it isnt enough, and not naming the real issue make for beating around the bush alot when the solution is quite simple.
Very good observations. Plants needs are different, hardscape does matter, water hardness, type of food, light. Algae can compete with plants when water is rich in nutrients and their superpower is the ability to convert carbonates when there is a lack of CO2, thus making plants losing the battle.
I got a little bba on a batch of vallisneria nana and the plant was a little unhealthy. I didn't think there was a correlation between the two.
Got rid of it with liquid carbon an a little trimming on the worst looking leaves.
This was really helpful - I've actually heard about the cross-contamination "myth" and you're right - I think it adds confusion. Who has time to disinfect between every tank? Also, can you introduce us to your kitty please? Such floofy goofy sweetness needs to be showcased 🙂
Contamination for BBA and any other kind of algae is nonsense, algae spores and water simply go together, but obviously fish diseases can be transferred so some hygiene is necessary sometimes.
It’s not a myth, where do you think algae comes from? It isn’t magic. It comes from spores and those spores are transported into your water externally because tap water is treated with chlorine to kill algae and it’s spores. All algae comes from contamination.
@@jc13781 Spores, like viruses float about in the air, yes very dry air will sometimes kill them, but normally even in very dry air, when they encounter warm moisture, we will see life. Algae grow on walls, trees and fish tanks. Spores can be in fish waste. Red algae largely but not exclusively from my 60 minutes of research this morning spread their spores in water, but I have no evidence that they cannot survive in aerosol like moist air, green algae and blue green algae will appear after you boil tap water, if you leave it on a sunny window sill, repeatedly done the experiment. I don't believe in magic, scientifically before Pasteur did his work it was called naively spontaneous generation, in fact as we know lots of small things are invisible to the human eye and can grow and be very dangerous. The spores of many algae and fungus are potentially deadly if they get into the lovely moist conditions of human lungs, so take care, but no magic. Hospital theatre air is filtered for this very reason. Google it if you don't believe me.
@@williammcdowell6257 ok so is it possible that bba spores are not native to certain areas and thus the spores aren’t floating around and as such can only be transmitted via contamination?
@@jc13781 That question is a bit out of my knowledge base, what I would say is that in a temperate climate such as the UK, season plays a very big part. But there are so many species of algae that most types are represented in most places, my goldfish pond gets BBA on the filter outlet and green algae especially in spring, but I have never seen blue green algae in my pond but I have seen it in lots of contaminated water bodies in the UK.
My own experience shows that BBA grows if you have too much CO2, as well as fluctuating. I dose CO2 with a CO2 controller, if I have a larger pH drop BBA appears, also when the bottle runs out BBA grows.... There is a happy balance.
Currently having BBA ever since I got a new more powerful light.it looked good but now I lowered from 12 to 10 hours a day and dropped intensity.it stopped the algae from growing but it didn't killed it.
Next thing I tried was some liquid co2 on the tank and on the plants with very minimum efect.
Yesterday I've done a big 50% water change and exposed my leafs and while cleaning my tank I put some liquid co2 directly on a few leaves with BBA and today I noticed it turned from black to a reddish colour but still attached to the leaves.
I'll keep you updated if it worked for me.
Exactly the same situation of me. Let us know. I’ll update from my side too!
I never had it before now , I have Amazon swords that keep dying so I added a kessel a160 with my florescent light and that got me black algae I’m going to try excel now
Hi I am setting up a new tank right now what do you think is the best aquarium plants for a 10 gallon tank? Thanks!
Yep, with high light, plants consume CO2 and if injection is inadequate yes BBA, the mystery of BBA on areas around filters, yes it grows there, but why? Lower CO2, not sure, big filters produce low levels of CO2 (respiration from aerobic bacteria) only surface agitation increases O2, or use of an electrolysis steriliser (which I have extensive trialled and found made no positive impact) Cleaning filters, only helps if significantly reduced flow from accumulation of not yet decomposing or partially decomposed material. Dirty filters are the best filters, so take care. As I have often said Mark, I won't use Glutaraldehyde. 2 Hr Aquarist site is excellent, though not quite for beginners. The ADA site is also excellent. For beginners and those who don't want to spend a fortune I definitely recommend a very unflashy little site from Wales which is not set in a shed but rather a basement of what I think is Victorian terraced house: ruclips.net/user/AquariumShed
I just got BBA 2 weeks ago, out of the blue, after 5 years of not having BBA. I did ALL water tests available. From O2 to Cu, to Fe, to everything available. I found out that our Tap Water, suddenly, starting mid October, had HUGE amounts of Silicates in it... Fixed the issue by adding a well-known material bag in my filter, and now it's gone :-)
Awesome! Good job doing those tests!
Silica is horrible in an aquarium some sand substrates carry silica and fish don't like it. So yeah great job in finding the problem. Btw how did you solved this issue?
Wow. Thanks for the information. I hate BBA so much.
@@aspinwallfamilyhomestead7018 The funny thing is that I don’t have sand. For some reason, our tap water every year on October gets high silicates. Yes I solved it by using purigen in my filters and when the silicates in our tap water get reduced, I will remove the bags again.
@@ChristosChristos okay that's cool where are you located? I'm in Georgia USA and I'm on well water that is going through a 15 micron then a 10 micron filter then I got my whole house water softener ending up with an 110ppm and a 6,5 ph lol I also have an RO installed for my discus tank who are swimming solely on pure osmosis water. So I don't have any problem with silica in my water. Although I want to add a centimeter of white sand in my discus tank soon and I am sure my ro water will filter any silica residue out during the daily water changes. But yeah cool to hear how you found it out and what you did to solve it
Ive getting an idea by others tht siamese algae eater or otocinlisus cat is good for BBA eradication frm the tank..? Any advice as I yet to encounter any but I hv those 2 fishes in the tank since beginning....maybe theyre solving the problem before i noticed it....?😊
Great video again, quick question ive just brought some plants online but my tanks not ready for them best tips to keep them in good condition? Thankyou
Keep them in a window, but not in direct sunlight.
Cover them with plastic wrap so they don't dry out
And spray them once in a while
@@MJAquascaping awesome thankyou
This always my problem. I was thinking to just redo scape entirely. Been running my aquarium for 1 year now. The water surface also my problem lots of gas so I installed skimmer and increased water flow.
Should I change everything from plants, existing soil, filter, stones?
maybe a video about dipping plants in hydrogen peroxide. I think that might be good since we're talking about bba
im sure i got my bba from the standard juwel light, 6500k and a whopping 9600k light combo, switched to 2 6500k's and already seeing less and more browner bba then grey
I use an syringe to applye the liquid carbon to the bba directly and after one day their colour changes from black to white and die with in two days
Yes. BBA or staghorn on my plants and almost none on my hardscape. No CO2 in the tank. Spot treatment with liquid CO2 before the BBA or staghorn gets out of hand.
I would check for Phosphate and make sure your lighting is bright enough and not on for too long. You might also find fast growing plants, especially surface plants will really help protect the slow growers which seem especially vulnerable to BBA.
cheers, just getting a break out under controll in my tank, (had co2 fluctuations and high light) also bit of green hair. would you bring nitrates back to 20ppm or keep lower ?
I would go lower
@@MJAquascaping thanks been something of a dilema. Really enjoyinging your content btw, excellent work :)
@@MJAquascaping I aim for
How about a list of fish that eat BBA ?
within nutrients iron is the main trigger for bba and i also noticed that, when undissolved co2 reaches plants/hard scape it can also cause bba.
undisolved as in actual bubbles hitting surface of ant structure?
@@intheframemedia yes, thats what i meant. it doesn’t matter how low your flow is it could happen. Mostly with slow growers and the scape.
@@apfeln seems to be what ive been observing in my tank
@@intheframemedia try to turn off the filter, siphon as much water as you can, wait like 5-10mins let the water movement completely stop then spot dose liquid carbon directly into the bba. Wait 30-60 sec then refill the tank. After 24 hour you should see the algae turning red/pink after 3 days white then it would disappear 100%. be careful not to let the carbo stay too long on mosses and fragile plants like hc cuba and most carpeting plants. Riccardia has 0 tolerance to liquid carbo avoid using on it completely. :)
@@apfeln thanks
👍👍👍🔥
Going back to this video to learn why my bucephalandra has black beard algae on it’s leaves 🤦🏻♂️ but tbh I’m not sure if it was bba
Should I need seachem matrix and purigen both as filter media or only purigen is enough.
Just purigen is fine
hello, can we use fluval stratum and tropica soil together ? :)
Yes, absolutely
What about marimo algae?
Using liquid carbon directly on BBA witch is prety much still alive. How long should I let i work until I start the filters again?
When BBA dies it turns a bit brownish. It usually takes a few days.
Yes I struggle with Bba my question is co2 shud my drop checker go frm dark green and Finish at light green and end of photo period of 8 hrs or should it get to light green much faster
Starting at dark green is usually ok, but it also depends a bit on how much light you are using
I didn’t know light played a part brilliant MJ many thanks 🙏 again
my dwarf hairgrass carpet is infested with BBA should i just mow it to the ground. or will it like die and disappear if i fix the cause? what if i poured benificial bacteria like ada bacter 100 in the carpet? i have two 13 watt lights on the tank its 10 gallons on canister filter i dont dose liquid ferts.
Fix the issues first, and then trim the carpet!
How do you clean your substrate if you have root tabs?
I just wave my hand over the substrate, i never really dig into the substrate
Can someone tell me the name or brand of the wooden/steal shelf at the background? Thank you.

@@MJAquascaping Thanks MJ 💚
When I first got in to the hobby I was 7/8 years old, by the age of 12/13 I was breeding live bearers and cichlids. I kept everything from guppies to Piranhas and Oscars. I ran all my tanks on under gravel filters as well as eheim external filters when needed. During the 10 years or so before leaving home I never experienced BBA, staghorn algae, Brown Algae, diatoms, or blue/green algae. I just got a bit of green algae which would simply scrape off. I often wonder why my tanks in those days were so algae free and easy to balance. It has taken me a long time to learn how to balance my scapes but still I get BBA or staghorn or some other type for seemingly no reason,,sometimes it just disappears and sometimes Ibneed to treat it. Is there some thing to be said for UG filters that prevented the more pernicious algae’s, and has any one had success using them in an aquascape.
What an interesting post which sadly I initially missed. UG properly installed always match the size of the tank, work perfectly if the gravel is not too large in particle size and the gravel isn't deeply vacuumed too often. As for growing plants...well with bright light and CO2 injection that might work, but an experiment I have yet to run. But UG with air operated uplifts and water high in phosphate do grow lovely algae, especially BBA espeically if hardwater is involved - BBA is expert at extracting CO2 via biogenic decalcification. Floating plants used, even the dreaded duckweed and matters tend to be more satisfactory. With soft water, good light and 'semi floating plants' Hornwort, Indian fern, I remember good results without BBA etc., from youth but then I moved to hard water area and have worked hard to grow a range of plants without occasional BBA.
No BBA issues currently, good CO2 levels, moderately hard water, good light, large canister filtration, plenty of floating plants and low phosphate and nitrate. Don't know how much my post helps, but I think the advantages of UG - easy maintenance, good water quality and no clutter around the tank, are often overlooked. As I age the bother of external canister filters, the dangers of fish death and inadequate medium in internals and I am tempted to revert to the plates, and if necessary settle for plants such as Java fern on bog wood and floating Indian fern, with CO2 injection I cannot see how it cannot work. Crypts love soil substrates which of course is a problem with UG but some claim success with deep beds and soil in mesh bags.
@@williammcdowell6257 that’s really interesting about hard water and BBA. I grew up in Watford and the water there is hard as nails, I never really had great success with plants except Vallisinera. Maybe this is an experiment for @MJAquascaping to trial. One of the biggest problems I foresee is that oxygen dissolved in the water is not good for CO2 injection, that said, most UG filters could have 2 uplift tubes( if that’s the right term) one could be used for CO2 during the photo period and the standard air pump when at night/lights off. Simple timers would work really well. With Auto dosing the flow of water would bring nutrients in to the soil/ substrate. If I had the space and time I’d love to give this ago. There was something really nice about the simplicity of UG. Today I don’t even see them for sale but could be made quite easily. There are so many species available to the hobby, a low tech set up with ferns, Anubias, Buce’s. With the knowledge I have now and modern day resources available I don’t see why this would’nt be successful. When I a youngster there was no soil just gravel and sand was rare except for Marine set ups. I think a good base of power sand or similar and aquarium soil would work great.
I have a low tech plant setup and the aqua-store nearby sold me the Masterline Carbo as the alternative to Co2 pills or Co2 injection (did tell me it won't be as good of course). So you're saying it does not dose the water with Co2? Its just to "kill" algae? :/
It does not dose the water with CO2
CO2 plastic bottles are a waste of time, follow Mark's videos and make yourself a simple yeast and sugar CO2 system - what is high tech about yeast and sugar, call it a nature tank, decomposition produces CO2 in lakes, fermentation is a living process also.
So called liquid carbon is Glutaraldehyde, look it up at your peril, banned in the British NHS. For liquid CO2 you need a steel tank and enormous pressure. CO2 is a gas at normal pressure, hence the greenhouse climate issue it is funny how we don't join up the dots sometimes. Some reputable planted fish tank product manufacturers point plank refuse to sell Glutaraldehyde and the top quality web sites don't use it, though some did in the past.
I found some resources says temperature can cause bba too? Is that true?
Yeah I think most algae grow faster in higher temperatures
Kinda frustrating when i'm using diy co2 but i need to use cooling fan to keep my aquascape temperature between 27°-28°C
I like 10 minute, even more video's.. ijs 😊
There is only one reason BBA is in your tank.
You put something in your tank that had BBA on it.
Isn’t it normal for the CO2 level to rise when the CO2 is on, and fall when the CO2 is off at night?
Yep! that's fine! As long as its just a smooth line you know
When injecting CO2 yes, other way round of course if no injection, plants respire when the lights are off and release CO2, watch out that fish aren't distressed when CO2 first comes and and plants haven't reached peak photosynthesis especially if CO2 injection comes on (as many recommend) and hour or so before lights.
As far as I know, CO2 and O2 levels dont compete in the water. So high flow and O2 rich water would not mean that the CO2 level in that water is lower. Open for discussions :)
en wat als je een aquarium hebt waar je geen co2 in gebruikt maar wel BBA hebt?
Waarschijnlijk heb je dan te sterke verlichting of teveel afvalstoffen
@@MJAquascaping kan wel kloppen, verlichting is een chihiros C2 RGB en staat op 100%, ik gebruik elke dag 1ml masterline AIO golden op een bakje van 30x30x30. ik denk dat ik men verlichting eens ga minderen en een dag ga overslaan met doseren.
@@BoostTimo Ja die C2 is behoorlijk sterk!
👍👋🇫🇷
Planting only tissue cultured plants, I've never had BBA.
Lucky that's all, don't think the culture issue makes much difference, algae spores are always going to be in a fish tank, BBA is not a disease, a point Mark was essentially making. Put a glass of boiled water on a windowsill - although you have killed all the spores by boiling, within a few days spores fall in from the atmosphere and grow, green comes first though.
@@williammcdowell6257 If I know correctly, Many red algae including BBA never infect tanks via air, its spore only survive and spread within water, not like green dust algae or green dot algae which spread via both air and water. That is, tissure cultured plant and quarantined lovestocks do matter.
@@OO-os5yv I honestly don't fully know, and will do some research. I have seen BBA in water without plants but can't honestly say that plants, hands, substrate didn't play a part. Thanks for the post.
@@OO-os5yv From a little research, you have a point. Thanks. The spores of Red Algae are specialised and carried primarily in water currents. However I can find nothing that says whether or not, like nearly all of the spores, bacteria and virus species so far studied, that they cannot be spread in aerosols., which is not the same as being everywhere in the air I agree - though arctic and desert conditions are a bit different of course.
Moist warm environments and even apparently the spray at the seaside can spread spores, and of course, human breath. But the spores can of course be in fish waste, and BBA is a common nuisance in fish only, high load tanks so though I think tissue plants are not a source, I still doubt that any aquarium owner can, during the process of tank ownership, keep it out indefinitely, even if fish are quarantined.
BBA can split the carbon out of hard water, it likes high phosphate > 0.5 ppm and high nitrate > 20 ppm and fluctuating or low CO2 levels, so control and even visual elimination is possible, my main tank had an outbreak last year, it looks free of BBA currently but I know that if let the CO2 fall or the organic waste levels build it will return and filter output pipes inevitably have some in sufficient quantities to be visible, in time.
I think you might have an experiment idea for Mark, set up three tanks, one fish only, one with tissue plants and one with plants from a tank with some BBA and see if the first and second tank remain free of BBA. I am not a scientist so I am reluctant to be too definite about things, but scientists know that they have to follow the evidence. Thanks again for your posts.
Let’s see this 7 reasons why I don’t have bba. Don’t have co2 nore do I have ever cleaned my substrate. Planted 135 gallon tank with fish lots of fish. Never used chemicals or have I ever dosed any fertilizer in my tank, do water changes every 5-6 months and just do a 45 gallon water change feed like crazy. Slow flow , all of the above contradict the reasons…. I’ll have to try the opposite of what I’m doing see if I can get bba. Maybe do water changes every three years since the last water change was two year’s ago. Never cleaned tools got new fish about a year ago from different places . Always doing the opposite of video. No rant here. Love the videos tho. Just too off water with bottled water and water changes are the same. Bottled water.
I swear every expert has entirely contradictory opinions on this :(
