- Often times aquarists focus solely on pH and find themselves chasing a certain decimal when understanding and measuring KH is what is being missed. In this video, I'll show what affects pH in an aquarium and demonstrate the why a buffering system for pH can keep your fish safe and your water parameters in check. Don't worry if chemistry isn't your thing, we'll keep it straightforward so you have a better understanding of what's happening in your aquarium!

soil is the best way to buffer water, which is one reason why dirt/soil is a good thing in an aquarium. good video. reminded me why my high pH, moderately hard source water is so good for me. soil is the way water is buffered outside in nature. my soil produces high PH water. that is the most important thing for me. It keep it higher pH
That’s cool - I still haven’t done a natural soil aquarium but definitely know people who have and they all say that it’s worked great. Thanks for watching!
Thank you so much for this video! I now finally understand.
Love to hear it! Thanks for watching 🙏
Thanks for the very interesting video and congratulations for the work you do
Thank you for watching!
I ran Calcium reactors for years on my saltwater reef tank. Always running a fine line between maintaining a stable pH and calcium level, with certain wipe out if you get it wrong or a valve fails.
P.S. If you really want to monitor your pH, I would suggest getting an electronic meter. Constant, real time data will yield the best results if you are really concerned about your pH levels. They are not that expensive and make your job much easier.
Thanks for watching! I agree - That electronic meter I used in the video is very cool.
Since when BRS has a fresh section? This is good quality I like it!
Hey 👋! Thanks for that 🙌. This channel is just a year old so lots more to come. Releasing shorts pretty often and longer educational videos like this one on Fridays. Appreciate you looking around and checking them out! If you like what you see, please consider subscribing 🙏
In the last sentence you kinda said that variation of Ph can harm fishes but I saw people from the hobby, going in the Amazonia south america and measure Ph at same spots, at different time of the day and some wild fishes live in water that can change around 3 to 4 point of Ph in 24 hours ! And they are very healthy ! But of course we can't compare to our aquarium but I think its interesting knowledge to share within hobbyist 😃
Hey! Yes, that is really interesting. Nature sure is wild 😁. Within the relatively small size of an average aquarium, a pH swing like that can certainly be dangerous for your fish. Thanks for sharing!
Very good tutorial. Very good breakdown of how to. I'm still confused a little. But it's me, not you! I think its because it reminds me of math. My brain doesn't do math! You did break it down and explained it well. Thank you for posting
Believe me, I get it! Don’t worry too much about the details, just the main point which is to remember to keep an eye on that KH! Thanks so much for watching! 🙌
I just do a "ghetto" CO2 system with a soda bottle, some yeast & sugar to feed my plants semi-regularly.
I don't care for fiddling with CO2, but I'll need to have a system for an upcoming 75g tank project, so that'll be an interesting challenge.
I have water that's basically liquid rock & I've found coral or seiryu stone makes the water harder (as demonstrated), but adding oak (because I have them all over the yard) & catappa leaves to my tanks & replace them when the snails & shrimp are bored of them & that keeps my PH to a lower, more tolerable level for all of my critters.
That’s super cool that you have a solution like that which works for you! I have a 75g in the studio with CO2 and actually am running two diffusers in different parts of the tank because it’s so big. All off of one regulator and tank - just two manifolds on the regulator. CO2 Art makes a great one for that. Love the use of the leaves - nice! I have those in a tank as well and they’re beautiful.
Pretty good explanation
Thanks for watching!
Where can you find a text kit like yours ✌️🙏🇨🇦
Here you go! Thanks for watching!

from my experience with planted tanks KH1 is ideal because it uses less CO2 to reach the target of 30ppm. As long as KH remains stable at 1, the CO2 ppm will not increase further to stress fish. Also, when the lights come on, the KH will increase slightly meaning the crush corals is doing its job to stabilise the KH.
KH doesn’t effect how much co2 is dissolved. Its only effects how much the ph swings from the co2. If you have 1kh vs 8kh your indicator solution will be different colors but you will have the same amount of co2 in the water.
@@873charlieKH may not affect CO2 concentration, but it absolutely affects its bioavailability.
@@StephenP2003 i was also wrong about the DC color change part… can you explain more about what you said though?
@@873charlie it's a bit complicated to explain in a comment, but there is an carbon equilibrium in water that's directly influenced by hydrogen (which is what ph is a measurement of). An equilibrium is basically a chemical reaction that can go in either direction. KH is on the right, CO2 on the left. The lower your pH is, the more the equation favors moving left towards free dissolved CO2. Otherwise the CO2 continuously converts to carbonic acid, which continuously dissociates into bicarbonate and hydrogen until enough hydrogen ions are produced to bring the ph lower... basically some amount of CO2 gets tied up in this dance between carbonic acid and bicarbonates. Co2 injection sort of makes this less of an issue, but where you really see plants start to suffer is when someone who has super alkaline water (like KH above 15 degrees which is more common in the US than people think) tries to set up a low tech tank. There are still many plants, however, that evolved to use bicarbonates and convert them to co2, such as vallisneria and elodea and dwarf sagg. But by and large it's a very inefficient process and most plants suffer to some degree when bicarbonate is practically their only carbon source. There are even a few plants, like some eriocaulon species, that just can't thrive unless your water is below 2 to 3 degrees KH.
@@StephenP2003 oh wow thank you. Luckily the plants i have seem to adapt well with my 12dgh and 7dkh. Hydrocotyle, buce, anubias, rotala, tiger lotus, and echinodorus.
On well water kH straight from the tap is 12. GH is 21 i belive good classifies it as liquid rock😅 yes i keep live bearers and cichlids
🤯 Thanks for watching!
Does increase in PH lvl changes the water colour to green?
Great question! A higher pH won't discolor water like algae/tannins will, for example. However, it can make your water cloudy but typical freshwater pH ranges should not have that effect. Thanks for watching!
Quick question , if I add crushed coil to my planted tank wouldn't that increase the pH and in doing so lessen the plant's ability to uptake nutrients?
Great question! Think about adding crushed coral as a pH stabilizer more than a pH increaser. In other words, the crushed coral creates a balance between what causes your pH to rise and fall. That's the job it's doing. Having the right balance of CO2 to the amount of plants absorbing it is also part of the balance. There are many things that affect pH in an aquarium, which is why monitoring KH is a better bet. If your KH is where you want it, you can be confident that your pH won't cause you issues. The coral gets your KH to that level. You are correct that a really high pH can decrease the plant's ability to absorb nutrients, but adding some crushed coral won't put you in that situation. The way I look at measuring this stuff is less of it being a pain and more of it being kinda fun :). For example, grab a kit, measure your pH and KH, add some crushed coral and measure again after a day or two. You can always add and remove until you get things where you want them. Enjoy the process!
I heard that adding baking soda also increases kh. Can this also be an option?
Yes that will work! Go slowly and test after 24 hours before adding more. You don’t want to move the pH quickly as that can stress your fish…also, dissolve in a separate container first!
I've thrown in a few pieces of coral I've collected in the Caribbean, will that do or must I buy the Aragonite.
Hi! That will be the same as Aragonite is basically Calcium Carbonate
This is the first video I've seen covering the actual meat and potatoes of what PH is and why what really matters is KH.
Good demonstration!
Thank you! 🙏
My kh is 8 from the tap. I have hard water
Wow! No kidding 😳
how do i use co2 injection with aquasoil if my ph is at 6.5
Hey! You definitely can - if you have an active substrate aquasoil (like UNS Controsoil) it will buffer your pH to 6.8 even with CO2. Your plants will absorb the CO2 as well protecting from getting too high levels. It does depend on what your fish need so if you want to go higher, you can add crushed coral to your filter. Lastly, you can buy additives that raise pH that you can also add to your aquarium if you needed to. Thanks for checking out the video!
@ the fish need min 6.5 will the aquasoil raise ph if it gets too low or is it only able to lower the ph to bring it down to 6.5 on the bag it says the range is 6-6.5 my kh is 0
Aquasoil will lower the pH to that target as plants typically prefer slightly acidic water. A low KH can result in pH swings so would be a good idea to get that up!
If CO2 lowers PH will an air pump with air stone raise the PH ?
Awesome question! Yes, adding oxygen to water dilutes the CO2 concentration which in effect will increase pH due to the CO2 having less of an affect lowering the pH. However this won’t be nearly as impactful as excess CO2 is to lowering pH. I run both a sponge filter and CO2 simultaneously in one of our tanks in the studio with no problem. Thanks for watching!
@BRSfresh I had steady 7.6 ph and decided to put an air stone inside my my fake wood decor that originally turned the water stagnant inside the decor because of no water movement. I drilled some holes and put the air stone in it. Then couldn't figure out why my ph was +9 Its amazing how any little change can affect your aquarium drastically.
Very true but it’s awesome that you’re aware if it. Your fish will thank you 😊
Crushed coral also increases gh, i already have quite a high gh, and hardness at high levels are also damaging?
Yes that’s true and you’re right, too high GH can be a problem for some plants and fish. Aim to stay in the 4-8 range - if your tap water is really hard running it through a basic RO will help tremendously!
