Help My Torch Coral !!!

[just fishings]

O.K......So someone tell me what they know about the torches and other related corals ( hammers- frog spawn ). I have had some torch in my tank for about 8 months. They first looked OK (NOT GREAT) but did open up and they even started spliting.....till now? The tentacles have for a while not been extending all the way out; some have even died now. My tank is 75 gal. with (2) 175- 14,000mh and (2) compact atnics. I want to open my tank up to more of these corals but with better luck. Any help.......Please !!!

What are your water parameters?

Well everything looks good with like using the master system. I thought that with them having a calcuim "shell" they may need more added to the tank; so i went and got the test for that. It was like 520ppm. I think it is suppose to be 400-500ppm....right? But would that make it not open and then even die? :notsure:

what do you mean by everything looks good. What are the numbers? No I dont think calcium is your problem.

The last test I ran everything looked good with the Kent test kits. I had the reef master kit. I had Nitrate; but very little. The first color up over 0ppm. I have added on a refugium tank to add in that problem. They have been like this for months. What are they sisitive to?
