Would you please elaborate on what you mean by "keeps everything in the water." And what the advantage is for doing this.

Before and during this "reef tank adventure" of mine I've read literally thousands of words on the subject,for both large and small reefs. As with any venture or hobby, reefs especially, one encounters all sorts of setups, some loaded with contraptions that work and others with the same gadgetry that claim it's all worthless. Same with additives. I'm sure there are as many ideas and methods for keeping a reef as there are reef enthusiasts.
I've read countless posts on these forums and other articles where folks have reefs with plenty of live rock, protein skimmers, RO/DI units, UV sterilizers, sumps, refugiums and perhaps even a CD player thrown in for good measure, and they're puzzled because their nitrates are 40 - 60 ppm, and their tank is being overun with cyanob and hair algae. The book says "no way" but they are proof that it can be so. I have personally seen, close up, tanks that have nothing but live rock and a protein skimmer - nothing else, that are the best I've ever seen.
I suppose each of us needs to confront and solve our own demons, sorting out the best advice from the folks who know best, our personal experience, personal past history and the uniqueness of one's own tank.
As long as I can maintain my water at the quality it is now, undetectable phosphates, 10 or less ppm of nitrates, the sensible approach would be to not touch anything. At least until I see disaster looming.
I appreciate the advice I've gotten from both of you and I'll consider everything. But for now, nothing changes. Many thanks. I'm cool.8)
