Sounds more like a bacterial bloom to me. It will likely go away in a few days if that's what it is. Calcium precip looks like tiny snowflakes floating around in the tank. FWIW
, I have found that the Kent Super dKH
buffer along with Kent Turbo Calcium works quite well to correct cal/alk
problems. You'll need test kits for both calcium and alk
before using it or any other remedy though. I like the Kent Tech CB additives to maintain cal/alk
levels. I don't have any tanks that are heavy calcium users though. If the bacterial bloom doesn't go away, assuming that's what it is, a UV
sterilizer will take care of it. You might want to run some GAC
as well for a little while.
