I was chatting with a well known member this weekend and the topic of water quality came up. This member has several incredible tanks dominated by hard-to-grow SPS. I was shocked when he told me he thinks RO/DI water is nonsense, a gimmick to get more money out of reefers. He uses tap water conditioned with Instant Ocean Marine Conditioner has his only water source, and has for many years. Again, this member has several incredible systems full of acropora, etc... and has never used RODI.
I would love to follow his advise and throw out my RODI unit but don't quite have the nerve. Does anyone else have experience (good or bad) with conditioned tap water in a reef tank??
