So bringing this thread back from the archives...this tank started with a plague algae of some type that no-one could ever identify...but since then, valonia got in on a frag and has completely taken over. It's overcome all but the hardiest of corals and has covered about 50% of the rock. I prune out a baseball sized amount each week and you can't tell I even touched it. I run a fuge on this plus GFO and Carbon (via reactors). I do have some phosphates...but still less than my main tank (which has no algae problems)

Any suggestions to deal with this? I have thought about taking the rock out to scrub it down but I have a pistol/goby pair and if the rock comes out I won't be able to get it back in through the sand...thus the pistol will probably dig out a hole and get crushed.
