My tank (125gal) is being chocked out with the green star polyps. About 6 months ago I removed (ripped) some of the polyp from the rock surfaces. I got hit with red slime and it took a few months to get ride of it. I'm guessing the polyps raised the nitride levels (due to the damaged areas). I don't know of any other way to remove the excess because the rocks are very large and can't be removed from the tank for maintenance. I cut the light period back to hopefully reduce the growth rate but I haven't noticed any change.
Any suggestions??? Jim
