Just ran out of reef crystals. I have a reef with mostly softies and lps. I currently don't dose and use my bi-weekly water changes to keep my params in order. There are lots of new salts and I was curious what the favorites are.
I've been using the Fluval salt. It mixes well and I tested it for ph, dkh, calcium, nitrite, ammonia, nitrate, and magnesium and it matches what they claim.
