notification icon so you don’t miss any more videos now I’ve been getting this
question a lot and a lot of people who first begin using pressurized co2 has a
little trouble understanding this concept and I understand it now I
mentioned this in the co2 series guy that I have but let’s go ahead and get
more into it and we’ll understand how many bubbles per second you will need to
inject co2 in your tank as well as how to measure co2 in your tank now first
off understanding bubbles per second and how much to put in your tank that is a
loaded question because a lot of people expect me to just give them a certain
amount of bubbles to put in their tank and just doesn’t work that way only
because there’s a lot of variables to understand how much co2 in check your
tank and how much co2 your tank can actually hold and that’s all dependent
on thousands of variables for example the pressure in your tank
how much lighting you have your platinum owed is such a cetera so there’s a lot
that goes into it so I can’t give you a direct number even if you just give me a
whole rundown of what you have setup on your tank now as always I always suggest
starting with one bubbles per second and it just up or down from there depending
on how well your plants are doing and depending on how much co2 is in your
tank now let’s go over this really quick a lot of people don’t understand what
bubbles per second is when they get into person or I see over – it basically goes
like this you take a look at your bubble counter and then you just count the
bubbles of how many bubbles go up from the bottom to the top per second so if
it’s one bubble per singing you’ll have the bubble go from the bottom to the top
in one second if it’s two bubbles per second it’ll be two bubbles they’ll go
from the bottom to the top in one second so on and so on and so on as I mentioned
before the amount of bubbles per second you can be putting your tank really
depends on a lot of variables one of them really is how well you’re diffusing
co2 and your 10 because that’s one of them
most important things that you actually have to watch out for and if you don’t
understand that check out this video here on co2 diffusion that I did in the
co2 series so how many bubbles per second of co2 do you need to inject in
your tank there’s actually three ways to figure that out and we’ll go over that
right now now the first way to do is actually a true and tried method which
is watch wait and see now this might be a little harder for people that just get
into using co2 using pressurized co2 but again to you once you get it down that’s
pretty much a method that you’re gonna go with this is basically all based on
observation so check it out this is how it works
so you set every tank set up your co2 system you get it going and you start
pumping one bubble per second so you wait a week or two and then to see how
well your plants are doing and of course make sure that your fish aren’t gasping
for air at this point you can actually determine say well maybe I could go
ahead and go with two bubbles per second and then see see how well it does you
wait another week or two and then just see how well it does and then you’ll get
the hang of it after a while and you understand how much co2 you put in your
tank and get that massive amount of plant growth as well as not kill
everything in your tank namely your fish now second way of doing it is actually
using a drop checker drop checkers are great they do work but unfortunately
they’re not very accurate because they’re giving you reading based on that
hour or two ago of what the state of your tank is or rather how much co2 is
in your tank now you probably see this all over YouTube you see these little
contraption they’re glass and they have a color liquid in it it actually looks
really really cool and there’s actually different types of drop checkers out
there the different makes and models and stuff like that whichever we go with I
only suggest using this as an indicator or if you just want putting a tank to
just look cool now drop checker works this way you take the drop checker you
actually put water and now we don’t want to use either tap water aquarium water
because there’s extra minerals in there that might affect the pH readings and
give you an inaccurate reading so you want to make a solution or use the
solution or buy solution on the market it’s called D kh4 which is basically
water that will measure @kh of four after that you put about three drops of
the solution that either came with your drop checker or that you bought
the market or if you already have on hand the pH solution in your test kit
and basically you just go ahead and put the drop checker in your tank and just
let it be and you basically just look at the color if it’s blue that means it’s
you measuring either no co2 or low co2 your tank if it’s green or lime green
that’s about the area that you actually want to be safe with with the level of
co2 in your tank and of course if it turns yellow that means you’re on the
high side of stuff and you better keep an eye on your fish now the third way of
doing this is probably the more accurate way of doing it and the less expensive
way of doing without going out and buying equipment to measure co2 in your
tank there is equipment out there that doesn’t measure co2 but that’s kind of
out of the price range kind of out of the range of what we’re talking about in
this video now the first thing you need is some way to measure your pH either
with a pH test skin or a pH probe or pH tester whatever it is you should already
have one if you don’t then I don’t know what’s wrong with you the second thing
you need is a KH test kit and then you’re going to measure your KH and your
tank first get a reading of the KH in your tank that’s it very simple once you
have that write it down then you need to take a pH reading you take a pH reading
before the lights and co2 goes on write that down then after a couple
hours when your co2 and light has been on your tank during the prime time of
your tank where everything’s growing and being active and stuff
do another pH reading write that down now the most optimal co2 you want any
tank is about 30 to 40 ppm now this could change and vary depending on how
your tank set up and how many plants you have going there you might be able to
put more co2 based on your plant load and finally take a chart that you will
find on the internet you can search is called co2 chart but I suggest using
this chart I have up on the screen this is what I got from tom bars forms and
this will do you well so what you do is take your KH readings and cross-check it
with your pH ring that you measure before the lights and co2 came on so
let’s just say your pH is 7.2 Year KH is 4 so you do a cross-check on that chart
now what you need to do is find out how many pH drops you need to get to that
target level which say in this case 30 ppm s let’s just make it simple now as
cording in this chart you need that pH reading to say 6.6
after the lights in co2 has come on after a while that was a second pH
reading that I mentioned now let’s just say your readings are off the chart your
pH is like 5.5 or your cage rule readings are like less than 1 or 0 if
that’s the case then you just kind of average it out based on the higher
readings on the chart itself and you can kind of figure out how much pH drop you
need of injecting co2 in your tank to get to by just looking at the higher
numbers now there’s a couple things you know about this method about this chart
basically 30 ppm is in the red boxes which says it’s a danger zone it’s okay
to go into the danger zone a couple boxes up it’s not gonna harm anything
it’s just gonna keep that co2 levels that you need in your tank however you
could even go up more but that’s again based on how well you have your tanks
set up how well your o2 and co2 equilibriums is in your tank if you
don’t understand that check out this video where I do explain that now for
cage readings in your water the water you’re using the source water using it
shouldn’t fluctuate that much mainly I only test my cage in my tank probably
every month or if something goes with wacky ok so it does change but not that
drastically unless they do something really weird to the city water if you’re
using tap water but you could be safe by just testing it maybe once a month just
to make sure that the cage is still either at 3 or 4 or whatever you have
initially measure do that and of course if you’re using RO water it’s going to
be much easier because you already know how to get to a certain cage level gh
level or whatever based on how much you measure on how to remineralize that
water now yes the last method was a little complicated to explain but it’s
really really quite easy once you get it down now once you get it down all three
methods here you’re probably going to use a mesh up I still have dropped
checkers in my tank even though I don’t really use them I do
just spot-check my tank using a drop checker otherwise I already know my case
in my tank I know it’s relatively going to be the same number for a while so I
keep it at that and all I have is my pH probe measuring the pH of the tank and I
could just I that while it’s going and of course using method 1 of ops
evasion of how well my plants are doing so you’re gonna mix up all these methods
when you get more experience in doing planted tanks it’s gonna be very easy to
adjust your bubbles per second to get those co2 levels to the perfect medium
that will make your tanks bloom it’s really that easy guys and then no you
can get it with a little patience a little more experience remember guys hit

already subscribe to my channel to let me know that making these videos it’s
actually well worth it love you guys and remember stay what would you tanks bye

is it normal for water to be slightly murky when using CO2?

Hello was just wondering what liquid you put in your bubble counter

6. Manuel T says:

Great video! Definitely your videos worth it!

7. Dominic H. says:

I can pump 60 bpm in a 10 liter tank, but because the KH of my tap is 20, I can not get more than 19-20 ppm of CO2 in my water. I start the CO2 at 7 AM, lights turn on at 9, and at 4 PM, when I turn CO2 off, my PH is 7.4 and my CO2 is at 20. Increasing the bpm is only wasting CO2. Fortunately, most plants, even the advanced ones do not "require" more than 20. Of course they could use 30 if they would be able to get it, but it's not a necessity for them to grow, they'll just grow a little slower.

I think this is the perfect balance for me. My endler guppies prefer more PH and harder water, and I can still deliver 20 ppm of CO2 for plant growth. If I had lower KH I could deliver more CO2, but I wouldn't want to make my fishes more uncomfortable so my plants would be more comfortable. People should put the needs of their fauna before the needs of their flora, a PH of 6.6 is insanely low for most species, plants and fish alike.

8. Hello There says:

More co2 in the tank the better. Only way its too much is if your fish are gasping.

Great video. Thank you.

I liek plantz

11. Matthew Voyle says:

Not about BPS but quick question for you. I am about to scape my first planted tank. Some of the plants I have available are not in great condition and have brown algae. Do you clean off the leaves or simply cut them away or would you just ditch them and start from scratch? Roots are in fine condition. Over to you

12. River Life says:

Beautiful tanks! Thanks for breaking down this semi technical concept.

just go old school…. a plastic bottle turned upside down and refill when it starts to fill in with water

Oh yes the fun of determining CO2 bubble rate. Ended up doing little bit my own thing along with some of what you have stated. Drop checker was what started to get me truly dialed in to where I needed to be for CO2 levels. Just kept it green and watched it all start coming together. Initially used a Yeast DIY setup for my CO2 with a powerhead to diffuse co2. Stayed with above set up but added an max mix co2 reactor powered by the powerhead. The powerhead and reactor was intank for this setup. Later added a second unit and dropped the bubble rate again. Inital bubble rate was 3 to 5 via powerhead, dropped to 2 to 3 bubbles with first max mix co2 reactor and finally dropped it to 1 bubble, maybe less, with the second Max mix co2 reactor added. Might have been less than that, I just remember the bubbles being really slow compared to when I first set up and the second set up with the co2 reactor added to the set up and then the final set up of 2 Ista's attached to the powerhead intank. This was for a 29 gallon tank that was packed full of plants, like Hollywood rainforest Jungle scenes levels of greens. Later did DIY CO2 reactor using PVC pipe outside the tank. Worked well for me so long as I watched the flowrate of water versus bubble rate of CO2. Used this DIY setup on a 10 gallon. Planning on doing an DIY inline reactor for my 30 gallon next planted tank set up. Just need to add all the stuff need since just added water after dry start method for starting my Dwarf Hairgrass

15. Colton Larson says:

I just set up a co2 tank. Regulator w/ bubble counter, PU tubing, a check valve, and a glass diffuser. I set the flow to 1 bps, and I can see it in the bubble counter, but can’t see it coming out of the diffuser. Is this because the flow is just too minute to see or is it more likely a leak somewhere

16. sunny cal says:

I have a co2art pro -se series kit with some accessories needed to get started with my planted tank. Your video's are helping me learn. I'm do worried I'm going to mess something up. Thank you so much for all your video's.

17. Austin DeFrancesco says:

Exactly what I was looking for thanks, very informative.

you are a god

19. Xhamthael says:

I have a 30gallon tank. How long should my Co2 be on? I have it set for 6 hours at the moment.

20. Victor Fox says:

5:10 "I don't know what is wrong with you." LOL, that's hilarious.

21. Jermain Leysner says:

My friend greath info i learn a lot of your video.. bless

I just bought a 450 liter aquarium with 2 external filters,can you tell me how i must setup them in mij thank?

22. Ufo Joe says:

Cheers mate, cool video. I still looked even if I have had a heavy planted aquarium for over 2 years now.

You're so right. Most important thing is observation. Fish and plants will tell you how they're doing.
I watch my tank for 2 hours sometimes and I can't get enough. I'm at 4 smaller bubbles/sec now but the tank is heavily planted.
I drilled a hole in the white intake pipe and put the co2 tube in there so all the co2 disperses evenly through circulation/ don't know if it the right thing to do… but the plants are growing like crazy.
You got good info in here, thanks again.
Have a good one!

Chung, I have a couple of quick (i hope) questions:
1) CO2 Drop checkers, is there ANY DIFFERENCE in the bell shaped vs. smaller ball shaped glass in tank drop checkers? (reliability, accuracy, etc. or no difference).
2) If given the choice, any all costs were equal or not a consideration, would you opt for in tank or inline CO2 difusser?

I'm looking at hooking up CO2 for my 29 gallon planted tank, using a Fluval 207 canister, and Fluval 3.0 LED for lighting, plants are doing just OK, looking for more lush growth.
I am also dosing with Seachem: Excel, Flourish, Potassium & Iron supplements, several times a week per bottle instructions.

25. Doris Coffee says:

im not trying to be stupid but I just set up a new co2, my first time ever and ive been watching your videos… Love them all!!!!!! My Question is, do you turn the valve all the way open on the canister or do you just open a little????? Ive got 1 bubble per second, (somewhat) but not action from the diffuser… have I don't something wrong???
