Calcium 400 - need B-Ionic?
Well, following the advice to look for the first abrupt color change from pink to violet, using the Hagen calcium test, my tank seems to have 400.
The first time I did the test I thought it measured much higher, but I was probably going too far in trying to match the violet color.
Anyway, should I add the B-Ionic 2 part solution, and, if so, how often?
I had been adding it almost every day for the past 2-3 months.
Live rock, live sand, fish, cleaner shrimp, algae critters, mushrooms and polyps.
