Will a RO/DI with a refuge really help out and keep water clean.[/quote] With pure water from an RO/DI unit it will contain your water quality that will keep things out of your tank that would be harmful. Distilled bottle water? cost what? 80 cents? I guess if you want to spend alot of money doing this you can but distilled does not compare to RO/DI purity. anything is better then tap water.
