Hey..thats fair. I mean if you have a nice RO system...thats great. I acutally have to buy my RO water (distilled). My parents have a Whirlpool RO system from Lowes and I used to get water from them when they come to visit. But it ended up that it was still to mineral heavy...my plants didn't seem to do well, there was a lot more algae, sphagnum didn't like it at all. The moment I went back to grocery store distilled water, the sphag has rebounded with a vengeance.
