I am new to the reef world. Started my tank in March and things have gone real well. The only thing I can not get to work for me is a 4 branched Trumpet Coral. I have a frogspawn, mushrooms, and some zoos that are doing great. I also have a pocillopora damicornis that has done real well for about a month and now looks a little down.
I have moved the Trumpet around and in one spot it seemed to improve but now is going down hill again. Not sure if its a calcium thing or what. I just ordered a Calcium tester so I can see what the level is on that.
All my water readings are real good. Its a 29 gallon tank and I do 4 gal. water changes weekly with RO water. My lighting is 4 HO T5's 30 inch long, two white and two blue.
Any thoughts on how to make my Trumpets thrive?
