My 240 has mainly softies, anemones and fish. My parameters are:
I have a coralline algae problem in this tank, coating the acrylic surfaces so thick that it plates. All fish look healthy as well as softies and anemones.
Q:Do I need to raise the alk in this tank to acceptable levels (8-9dkh) for the health of the fish/softies/anemones? or is the alk mainly used to help build skeletons for sps and lps? Can I leave this alk low like this indefinitely without harm or is there something looming?
I'm thinking if I raise the alk in this tank, my coralline with become even more of a problem, but if it's a health issue, I'll do it.
