I have a test kit with both KH and PH tests, how exactly do i figure out how much Co2 I have in the tank? And will argonite sand (crushed shells) have any effect on those levels?

3.6 x KH (in degrees) x 10^(7-pH) is the formula to use. Example pH=7, KH=5. 3.6 x 5 x 10 ^ (7-7) so you would have about 17 ppm CO2.

Or if doing all that math is too much like work, you can use one of the charts on the link below.

Vince ,Is that a picture of your setup. I never saw a regulator quite like that and is that a bubble couter attached to it on the right side? Who makes that setup? or did you build it yourself? Hows it working for you?

ya its my setup, the t handle type reg was to much of a pain , so i found a used, but rebuilt flowmeter. Its not a kit I put it together my self. I had it in my 37gal for 4 years and its been on my 125 for a year.
