Hey guys, I'm staring a new build and I'd like some input. My tank will be mostly sps. I currently have two sps dominated systems and have tried both kalk and 2 part dosing. In ny new setup I will try and use kalk as one of my primary methods to maintain my Ca.Kh levels. I'm sure kalk will keep my dkh inline (8-9) but to bring my calcium up I will be using randy's recipe dispensed through a BRS dosing pump. I would like to hear your experiences and possibly see some of the kalk sps tanks!
