Okay. So, now, how do I get the go ahead from the wife to buy a unit? Like I've said, I tried the pure drinking water idea, and that didn't work. I currently use dechlorinated tap water. I only have some mushrooms and polyps and a small leather coral in the tank along with some small fish. But, I battle with cyanobacteria outbreaks. I know the RO water would help alot.

Oh, by the way. She really doesn't like the tank, either. It's not like she hates it, but if it were up to her, it would be gone. Any ideas now?!?
