I know that the phosphates are high and the nitrates. That is the problem right now and that is caused by using tap water for the water changes. I don't have the money for an RO/DI system. But that is in the plans for the future, the joys of military pay it is not that much. Lights are only 3 months old and those are in the plans to be replaced with a t5 setup of some sort (probly mid month). Photo period was redused from 8 to 6 hour when i started having the problem, now the period is at 0 for the next few days. As for feeding I only feed once every 2-3 days, and only as much as the 5 fish can eat. Total flow in the tank right now is around 600gph, once sump is done it eill increase to around 1000gph. I do weekly 20% water changes but again not with RO water, I know that this is causeing some of the problem if not all of the problem. I also have cruched coral as my substrate, put this in before I knew better. The pictures are missing another 25lbs of rock that is finishing curing as I type this.
