Hi. I've been using Kalkwasser in my 120-gallon mixed reef. First I was using Reef Blueprint Isol8:Ca(OH)2 1000g - Kalkwasser, and when I tried to reorder it wasn't in stock. I switched to Coralme Kalkwasser. now It's time to reorder and I'd like to know the goto brand most reefers are using now with fairly stable results?
