I have have not changed anything with the lighting, I added some pH buffer Monday afternoon & I am going to check it again today. I have had the Xenia for about 6 months and the problem just started, I did recently add a heater & have it set @ 78.

I did a water test & the only thing that was off a little was the pH Nitrite - 0 ppm Ammonia - 0 ppm nitrate - 0 ppm pH - 8.0

Sorry for the bad pic, but can anyone tell me what is wrong with the Xenia? It does not seem to pulsate any longer & it looks like it is about to detach from the rock.

Thank you everyone for your response - it was all very helpful. Thank you Sundra for telling me about this site - it is awesome & everyone has been very helpful.

I am new to the hobby and the recent cooler weather made me wonder what is the best water temp for a Saltwater tank? Any help would be greatly appreciated.

I am insterested in some of the small rocks w/ zoas & other types of polyps. I am in Wells Branch & I can come pick them up afer the UT game. Please let me know what time will work good for you. Thanks Keith

I am fairly new to salt water tanks and I need some advice on algae. I have a 33ga tank that has been running for roughly two months. I have some live rock, mushrooms, xenia, 2 peppermint shrimp, 1 clown fish & 1 Yellow Tang. I first started to get a brown algae all over the live sand, some of it went away but then I started to notice in the back of the tank that the algae was turning a reddish color. Then two days ago a notice in the front a small patch of a blackish algae but this algae had as my son explains it "little hairs" growing from it. I did a water test and everything was perfect & I am doing a 10% water change every two weeks. Is this normal or do I have a problem on my hands? If this is a problem, how can I fix it? If this is normal, how much longer will this last?
