I recently ordered a LPS frag from a company that, turns out, isn't all that great. Seems that they frag as they get orders in, so that's a bit unfortunate. However, the coral has also taken a beating in my tank. It's been jostled around and dropped off the rock a few times. It does seem to be doing alright, as it has tentacles out nearly all day and all night, and still has pretty good color. However, I noticed some brown algae growing on the skeleton on one side of the frag. Should I treat the area with peroxide? I've treated soft corals before with good success, and I'd guess that as long as you keep the peroxide off the flesh you'd be alright. Or should I leave it alone? Obviously, the root issue needs to be solved, and I'm well on my way to fixing my nitrate and phosphate issues. Nitrates are climbing to just above 10 every week, and Phosphate has been topping out around 0.1 PPM. Trying to cut my phosphate down by about half. Weekly 50-70% WC's have been the routine for a few months. Any advice?
