I put 2 different drop checkers in my 10 gal. tank to compare results and see what level I'm at. One a CalAqua
Labs nano, one a Up-Aqua model. I get substantially different readings on the 2,the CalAqua showing blue, the Up-Aqua showing yellow. The CalAqu uses only the reagent, no aquarium water. The Up-Aqua using tank water and reagent. Has anyone else made this comparison, and what do you think might account for the difference? Is there a better method to verify the CO2 level?
