Reverse Osmosis or DI?

1 Answer

I have a choice of getting local RO or DI water from a local vender. I fill my own jugs. It is cheap. Only .33 per gallon. They don’t offer a RO/DI water only one or the other. The DI water is filtered through carbon before going through the DI unit. At this point I do not have the funds to buy my own unit so filling my own jugs works best for me. My question is, “Of the two choices (RO or DI) is one better than the other for a marine reef tank? I have been using RO but was told DI has less phosphates and silicates in it?
