I am looking to reduce costs of di resin for my ro unit, i need it for my reef tank but wondering if i can get away with tap water for my freshwater tank.
ive always used ro/di for my Discus but now its planted im looking at the tapwater, Kh is 12 dkh and GH is 25 dgh, is that too high for my tank to use as straight tapwater?
