Hello Reefkeepers,

A couple of days ago, I read in a thread that a reef keeper was having trouble growing corals and frags, several reef keepers responded by saying that maybe his water was to clean, what does that mean? Can water be to clean and effect the growth of the corals, I mean is it not the goal of a reef keeper to have water free of any phos, nitra(i)tes, water changes w/ r/o water, etc. So are we not to have uv, protein skimmers, or not use r/o water and all that good stuff that actually is what keeps the fish and corals healthy. my corals grow at very slow pace but they are healthy along with my fish. I try to do regular water changes use always r/o water and do not overfeed, so again what is having water that is to clean and affecting the growth of corals, because I do noticied that at pet stores or other friends that do not use r/o water their corals thrive and they I now for sure they do not do regular water changes, and myself that I get paranoid when a water changes is due or I start seeing a coral not opening do the right things to correct the problem(s) suffer.
