Right...so if I cut down on the food a bit, and perform more water changes it should lower the nutrients, no? Not sure what SPS is doomed means...are you saying that once the browning occurs that it is impossible to reverse? The browning started when I started feeding a bit heavier. I was feeding heavier because the tang was dominating the other fish at feeding time, and I was concerned that the other fish were not getting enough to eat. Instead of overfeeding I will attempt to put the vortechs on feeding mode, and feed the tang on one side of the tank, and feed the other fish on the other side, while the tang is occupied with the other side...
