I feed coral frenzy and ReefRoids and my sps grow like crazy. I could swear I see new growth each day on one of them. I do feed a lot though (each day) because I also have filter feeders, but I have no nitrates and phosphates.

I would suggest you to try reefroids and coral frenzy and also if you can get the zeovit amino acids and coral vitalizer you will probably see some major improvement.

Your calcium is low as many other people have mentioned here.

Actually corals do need a certain amount of nitrates for their growth and they will even use some phosphates but fish poo isn't just nitrates it is a food source for many organisms in your tank


My calcium is chronically low, around 360 and occasionally down to 320-340 and I have fantastic growth so I don't think that's it (although I do notice things don't look quite right when the cal is down at 320)

I've noticed my mg drops a lot in just a week. like 100ppm. I add more of the brs mg than the other 2 (volume). Best of luck hope you sort it out your tank was a beauty.

I have 36 fish in a 150 gallon display They all get along and my sps grow well..... maybe the fish poop is good. I try to feed about 4 times a day.

Ya, my Ca is good, I've always kept it around 390 -410. Anything over 360-370 is fine in a stable system, the advantage of having at 420 or higher is just as a buffer zone incase of a spike downwards.

I could probably feed the fish more, but again, I don't think that's a major contributor. I recall one member that used to come here had one of the nicest tanks ever, and he almost never fed his 3 or so fish. No supplements for the corals either....
