Is RODI water more so for the coral or the fish? It seems the coral are far more sensitive. Freshwater aquarist to my knowledge do not use RODI units. I know it’s obvious they’re fresh water please spare me the sarcasm, but the quality of the water, wouldn’t it be the same? Are freshwater fish not affected by the metals, or chemicals used by plants that make our water drinkable? Shouldn’t they be using RODI units or again is it mainly for “reefing?”
