I went out this morning and bought a Sera CO2 test kit. I thought it
would be like any other test kit where you fill it up a certain level
and put some drops in a test tube but this kit is different. It goes
inside the tank and constantly gives you a reading based upon the color
of the solution inside this plastic pyramid it came with. Will the
phosphates in the tank still obstruct my readings? BTW the java moss
was alreading pearling after the light was on only 45 min! ;-)
