I am dosing daily with a two part alk and calcium supplement and have kalk in my top off water. I have trouble keeping things stable. I recently added acropora to my tank and I think they are unhappy with the instability. The other coral seems fine.
The two part gets my alk and calcium where it should be but I think overnight the kalk is making my ph spike and my alk drops for some reason. Should I just do the two part and forget about the kalk?
