Instant ocean reef crystals

That is complete nonsense. I've been using reef crystals on my sps dominant tank for almost a year and it mixes just fine with rodi. I used to use just regular IO and it worked just as well so I may go back to it once my current supply of reef crystals is gone.

I mix my reef crystals with 10 stage RODI and it always mixes clear, I'm going back to reg IO cuz I still have to dose so it's not worth the extra coin.
