Xenia Frag

[Dorkel Marine 1]

Hi everyone. I purchased a xenia(pulsating) from Wendall about 4-5 months ago. It was doing ok until it took a few drops because of crabs in a row. I found the xenia upside down way in the back. It was quite an ordeal to retrieve him and maybe I hurt it. Now in retrospect I would glue or secure the frag better. Ever since the last fall the frag has not been doing well. The water has not changed at all. I've put it in a few different places but no change. Now I'm just thinking about adding kalk and monitoring calcium, iodine and magnesium plus keeping the alk at a certain level. Maybe because these level's haven't been checked or changed the xenias requirements haven't been met. The other corals I have are mushrooms, a colt frag and a greem star polyp frag. They are all doing fine. Do xenia have certain requirements. I read how they are viewed as weeds but maybe they are weeds in a certain environment. I'd like to know because eventually I do want some xenia. My goal now is to check the parameters pertaining to alk and calcium. don't get me wrong. my ph is steady at 8.3. There are next to no nitrates. A skimmer is now working on my tank. The salinity is at 1.025 and temp is approx 82 to 84. Is the temp to high. I read an article that said this was the average temp in the oceans where all our creatures come from.
