Using this Red Sea Drop Down Checker
I have been using the Red Sea Drop Down Checker to get an idea of the ppm of Co2 in the water. ( I know that the plants and fish are the real indicators- but am trying to get to around 30 ppm due to algae.) After increasing Co2, and using 4dKH water, in the DC, I seem to be encountering a problem.
About three to four days of being in the tank, my solution in the checker turns from green to clear.( I do put 2 drops of solution per instructions.) This has happened twice. The first time I thought perhaps the DC itself was not closed or sealed properly and the solution leaked out. Now I see that I still have 1ml of liquid in the DC, its just clear.
Has anyone experience this?
