I have a 110 gal salt water aquarium, MH lights, sump filtration, all water tests well within Perfect range. 20 gal water changes every 2 weeks, complete change every 6 mo. unless testing says different. Contents - live rock, snails, 3 hermit crabs, 2 cleaner shrimp, 2 clowns, 2 cardinal fish, 1 tang, 1 anemone, 1 tube anemome, 1 tube worm, 1 arrow crab and several Kenya trees. Oh YEAH! Bristle worms too! My red Flowerpot coral got over-heated last summer and is now a pretty PINK. Recently it seems to have (I think) a red algie slowly over-growing her. It's approx. 1/16 inch thick and looks like I should be able to just peel it off but I'm afraid of doing more damage to her. She is about 1&1/2 yrs. old which I have heard is pretty old for a flowerpot. I don't think a pic. would really show anymore than what I could tell you. ANY SUGGESTIONS???
