Glenn, balancing the bacteria in our tanks is difficult.
Some eat the nutrients which algae love, and some eat those which Cyano loves.
This is why I'm on this new trek to find what product will add the necessary bacterias which will out-compete nuisance stuff, yet still keep my SPS happy by not out-competing them.
Thus far, adding nitrogen and phosphorus has fuelled the brown crap, so I stopped that dosing.
I've also tried dried coral foods and phyto foods. Didn't document any change as that was all happening during the liquid dosing phase, so was all part of the ugly after-affects.
Since then, the only thing beyond frozen foods that has kept my corals happy-ish and returns their colors is liquid amminos. This still fuels the brown crap, but at a much slower rate, and my SPS are finally starting to look 'correct'.
I'll report back when I find which bacterial additive works for me.
