I have the same stuff. Pain in the a** to get rid of. I have a queen conch that eats it and a goby that munches on it. But the stuff was spreading so fast that it didn't even matter. I got some stuff for my filter to remove the phosphates and we had a death in the family so we had to go out of state for 2 days. The lights were not on for this time and the stuff vanished. But when I turned my lights back on I could only run them for a few hours and then turn them off and slowly increase my lighting schedual. It is pretty much gone now though.
