I use r/o water for water changes, tested for copper and it is zero. I do use sinking pellets and they do eat it. Calcium seems to be lowering slowly, It is funny because I use to dose every couple of days now I haven't dosed in two weeks and it is still high. I have a lot of empty shells inside the tank.
I have 3 shrimps, 6 turbo snails, now down to 5 hermit crabs (red, blue, haloween crabs) 2 clownfish, 1 yellow tang, emerald crab, porcelain crab,
Maybee it is my test kit that is the problem?
It is only 6 months old (API drip test kit)
