How are the Captive purity RO/DIs? I've been using tap water for top off for sometime now because the water is pretty good. Only thing is i recently started to find measurable amounts of PO4 plus the silicates are off the the charts. I get pretty frequent diatom blooms and i'm sick of it. Does anybody run these and are very happy with them? I have a dominant sps tank with a few softies.
