I am back into reefing after ten years. I have a new new place in Illinois with really hard well water. I tested the AKalinity at 11 and the calcium at 620-660 with a Salifert kit. I have two clownfish and a few shrimp, snails, crabs. At this point, will I ever have to dose calcium or alk.? I am waiting on a mag. Test kit. I do run an r/o unit. Is this unit now working well? Should it be taking out calcium too?
thanks for the help.
