ive had absolutely no issue's in using them.other then clearer water, not having to clean glass but once a week. My sps look great my lps are doing good and so are my zoa's. Been using them around 3 months myself, i use the vertex brand and the vertex uf-15 reactor for them. You do need to have a good skimmer, i suggest reading the thread on reef central. And if you decide to go this route, start off with half the recomended amount, dont cheap out and try to use a phosban reactor for them. And read on them. Don't let 1 or 2 positive or negitive comments sway your decision
