I have a "Fresh Water Master Test Kit" from Aquarium Pharmaceuticals. It tests PH, KH, GH, Amonia, and nitrite. After I know this I put the numbers into a chart I found on "The Krib" and it tells me CO2. I have to go to the dry tab kit I use for my salt water tanks to check nitrate. This kit is also from Aquarium Pharmaceuticals.
