Beautiful set up. I have had a few in my day. I still have one one of Bettas has tank that only has a heater in it. No filter. His plants filter his water. I use many house plants that live to hydro grow. He has fast growing aquatic plants as well. His tank is very balanced.
Yo, your videos are crazy chill. Could you do an @MJAquascaping megamix with only your chill music and clips of your tanks, closeups and zoomed out. No education, just beauty. With your voice also, talking us through it, cuz you've probably got the most chill voice on earth.
i _love_ how you mention that these tiny tanks aren't suitable for fish. i see so many "fish tanks" at the store that are too small for any species and it makes me sad to think about how many people put some fish in there without doing the research. beautiful build! the shrimp look happy imo.
@@stevecarrell8765 fish require roughly 2 L (1/2 US gal) of water per cm (a little less than half an inch) of length. even a tiny fish would require a tank much larger. now take into account that many small fish are schooling fish, meaning they need tank-mates, and now you see the problem. fish have quite large habitats in the wild, and while it's impossible to recreate that, we have to respect the minimum requirements for their well-being. think of it this way: you wouldn't force a dog to live in a crate its whole life, so you shouldn't force a fish into the same environment. hope this helps! have a nice day :)
@@Plough78 i'll consider the bora bora rasbora as an example, as they're extremely common in aquaculture and have a very fun name. bora bora rasbora get to around 6.4cm, or 2.5in, in adult length. a single rasbora would therefore require 12L of water, or about 2.5 gal. rasbora are schooling fish and cannot live happily outside of a tight school, so count on keeping at least five, but preferably eight or more. that means, at the most conservative estimate, you'd need a 60L (approx. 16 gal) tank to house them properly. tl;dr is no. tank's too smol.
Look at the bubbles on those plants! They are pumping oxygen into the water like no pump can do. When you see bubbles rising from plants, you know that the person who owns the tank has done a fantastic job making an environment which is healthy for plants. Such an environment will also be healthy for whatever aquatic life you decide to add, whether it is fish, invertebrates, amphibians, or nothing else at all. What a perfect environment! Great job! Thanks for demonstrating this art for us. it is the perfect mix of art and science!
Great tank, especially because it can be viewed from so many angles, would love such a tank on my desk. This is like many other no filter tanks give me a relaxing and serene vibe.
Thanks for all the amazing videos MJ. I'm not in a position to build my own aquarium at the moment, but watching your content is almost as good. Have a great Christmas!
You have a keen eye for good composition, and your knowledge of hardscape, substrates, plants and fauna is extraordinary. Thanks for posting. Great content, production and presentation! Cheers.
i dont know how i didnt know you already, been looking at aquarium videos in youtube for several years. Just suscribed, amazing video! I lived in the netherlands for several years, and you have a small dutch accent. Love hearing you speak, brings back so many good memories!
I reaaaaally, really love your tanks! I was searching for a long time for someone who makes, too, "no filter-aquascapes". Because that's what I do! So I really need inspiration for my Nanoscapes.
these are lovely little tanks. but for anyone looking to start out, small tanks are very delicate and hard to keep balanced. MJ is a fish in real life and can make it look easy. Please, if your new to the hobby, get the biggest tank you can afford /fit.
I have a tank in which I've thrown plants from a tank that I redecorated.They have been in there now for 2 month without a water change as I'm busy with work. I only topped the water up a little when it evaporated. The water is crystal clear, no algae and smells nice and fresh.There are a lot of plants in there I have to say.
@@Tdogg819 I think it's less about us seeing it, and more about nobody wanting someone's logo etched into their tank. It's a bad look, and probably turns a lot of people away from buying from them.
Oh ps: thanks so much for clarifying about the no-filter setup approach, it really helped :) Stunning tank today MJ, have a wonderful Christmas my dude :)
It's truly a testament to your aquascaping prowess that that unsightly FZ logo becomes completely unnoticeable in the post-one month tank shots! All I see is plantsplantsplantsplants
Awesome setup man! Super healthy and vibrant. 2 Questions for you: how do you ensure the moss and smaller plants don’t float to the top after adding water? 2: have you tried a tank with 1 inch garden soil and 2 inches sand to try and cycle the water quicker?
The outcome is fantastic. Considering something similar but also incorporating some pothos to hang down-outside the tank. Super hardy plant, easy to find and propagate by cutting. Thanks!!
Your videos are so great! I have a shrimp jar which has an airstone but realized I may not need it as there is a lot of dwarf saggitaria taking over and creating oxygen! Great tips and always love your nano setups
This was awesome! I was just wondering about the fern you attached to the top of the branch on the right. I couldn't find anywhere in the video where you explain what type of plant it is or how you attached it.
Beautiful setup! I do have concerns about a no filter tank - will the oxygen levels be enough? without constant surface agitation, I'm just afraid the animals in there might suffocate. Or will the plants generate the required oxygen within the water?
The idea is that the plants will generate enough oxygen, and toward the end of the video you can see oxygen bubbles coming off of them which is a very good sign.
You mind sharing your light schedule as I have been struggling in keeping my plants alive and fighting algae/biofilm And tips or trick for beginners? Or what are like essential/fool-proof plants? I just want a decent planted tank that won't just die after just a or two month 😢
I just found your channel. Lovely tanks and I like how you display them. You don't put too many tanks, so the viewer can see each individual tank. Nice arrangement
Nice cube! I let a glass cutter create 50 aquaria from my time I kept Betta's. I started breeding these HMK, but their kids all had massive tumors after trying to raise them which demotivated me so much I quit fish keeping for years. Slowly starting again with shrimps now, already bred 50 this year so far. I don't like the "red" plants, they turn brown.
I need like a 5-7 gall version of this for my pregnant guppy. Right now she’s isolated in a 6x5 isolation cube in a 20 gal due to too many agressive male and female gups in the tank but I wanna do a smaller planted tank just for her and a few shrimp/snails so she has a better deal. This is a swell idea, think it would be suitable for a single guppy at the 7 gal size?
Tip, wist je dat je aquasoil met een magneet kan oppakken. Ik zag dat je het met een luchtslang opzoog maar wat nog veel makkelijker is met een stokje en een magneetje aan het uiteinde. Wel zo handig als je een mooi zand padje hebt en er aquasoil geknoeid ligt. Zo zuig je geen zand op en blijft de boel netjes.
Heb je ook een tip tegen algen? Heb inmiddels meer planten in mijn aquarium (wellicht niet genoeg nog), gebruik af en toe algumin, heb algeneters en garnalen erin en ik heb alle stenen afgeschrobd. Alleen toch raak ik niet alle alg kwijt. Is groen van kleur (joh), en niet van dat draad of baardalg. Maar gewoon wat ook wel eens op de ruiten zit en/of het filteromhulsel. Ben al een tijdje opzoek en probeer vanalles maar de gouden tip heb ik nog niet gehad of ben ik nog niet tegengekomen. Hoor het graag!
Hey, love your aquascape video, but i have a question, is it safe to just put plants in aquarium with their pots (it's terracota pots with soil in it not the plastic one)? Or you must take them out of their pots and plant it in soil? Sorry for my bad english
Not sure if you still read the comments to these videos, but I would HIGHLY recommend using superglue accelerator + gel type superglue instead of cotton pads etc. Its a game changer.
Great, very inspiring work. Thanks to you, I'm going back to aquaristics and am now trying small and low-tech instead of big and high-tech. Maybe you can answer a question for me. Do you harden your osmosis water when you change the water on the desktop cube? If so, to what degree of hardness and by mixing it with tap water or do you use hardening salts? Thank's a lot!
Hmm the nutrients from the substrate will probably be gone after 6 months to 1 year depending on the brand and quality of the substrate. But if you keep some shrimp and snails their waste (poop) will also provide nutrients.
Hi, really healthy aquarium. I just start with my 10L desk aquarium. Can you tell something more about fertilizer for no CO2 no filter aquarium ? I have both from Tropica, should I use as recomended on the bootle or less ? btw I am from Venlo ;)
Enjoyed watching your videos. Well done and good information. I am just about to start my no filter planted tank this weekend. Hopefully it turns out as good as yours.
If it's indoors it shouldn't be a problem but you can put a lid or a fine mesh cover on top. If it's outdoors then you should consider getting some low maintenance fish that will eat mosquito larvae, such as rice fish/medaka.
@@ThePlantedTankTV I usually don’t, but for this video I just boosted the colors and the saturation a little bit. I noticed that after uploading the video to RUclips the colours and the quality goes down a bit.

Beutiful aquascapes i would like to ask Where did u get your main shelf?
A gorgeous little tank
When you did the water changes did you add stability each time?
Host you can make such grow without CO2?
Nice tank. I am thinking of setting one up for my office room. Is CO2 not required for a tank this size?
Is this an asparagus fern in the rear right corner (emersed)?
How do you achieve that kind of plant growth even for difficult plants without co2 injection?
Beautiful.
What's that poking out of the water in the back right corner?
Watching this during the last few minutes before Christmas. Thank you for this, MJ!

The plant soil contains too many nutrients and will cause algae.
looks pretty awesome! You could use a strong, litte magnet to catch the soil in the front.
Do you have any recommendations on which magnet works best? I'd love one for my tank. Thanks!
What glue is best for inside aquariums?
Regular superglue is what everyone seems to use
Coś pięknego !!! BRAWO !!!!

Do u have oil on the surface? If there is, do u do anything to get rid of it? Thanks
Nice cube. And how do you fight with an oily film on the surface in an aquarium without a filter and a skimmer?
I find that the oily film usually disappears after the tank becomes stable. Both the XXL vase and this mini tank do not have surface scum anymore.

Hi, how about the problem with mosquitos in no filter aquarium, how do you deal with that?
If it's indoors it shouldn't be a problem but you can put a lid or a fine mesh cover on top.
