Plumbed my new tank on the weekend and filled it up with tap water to check for leaks, see if it is quiet. It rocks! So now my question is should I empty the 125g of tap water (chloramine, TDS 300) and start over with RODI or just add salt mix to the tap water? Do I need to add a dechloraminator? Plan is to get saltwater circulating and add very fresh live rock and sand in two weeks when my students are back from spring break (classroom tank). Tomorrow I will test nitrate and phosphate of the tap water in the tank to see what they are.
