i need to raise my alk fast. Many off my corals are looking very ill. I tested and my alk was at like 5dkh and it needs to be at like 10 I just recieved SeaChem Reef Builder, SeaChem Reef Complete, and SeaChem Reef Buffer from Dr. Foster and Smith and have dosed the tanks once. Does anyone have experience with these supplements? How long/many times does it take to get your levels up? I will test again but am sure i need to dose again. The bottles say to dose twice a week, can more be done? I just dont want to lose any coral. I also have Kalkwasser, but am not really wanting to use it cause of the possibility of destroying my tank by overdosing.
