co2 question - Aquarium Advice

WaterPond · 01-03-2007, 09:26 AM

I know that one is to aim for 30ppm co2. Well, i am a little bit over at 34ppm. I have also heard that anything over 100ppm will kill the fish. So does this mean i am ok, if i keep an eye on it and make sure it des not go up?

34 ppm is fine. Lots of folks shoot for 35- 40 to compensate for test kit inaccuracies.

Sorry for jumping in here, but what is the best way to test for your CO2 level?

you need a co2 calculator, you can find these on the internet. And you need to know your KH and pH, not sure exactly what math they use.

The formula is as follows:
CO2 (in PPM) = 3 * dKH * 10^( 7-pH )
