OK I am really at a loss. I keep trying and keep failing.. I have a bunch of acan frags. They start off looking amazing, plump and juicy and stay that way then for no reason i can tell they start to shrivel up and die. Takes a few months but can't get them to recover after it starts. I have a bunch of corals in the tank and all do well. My Chalices are growing like weeds Zoas look great and all my frogspawns and torches and bubbles look healthy. I am just not able to keep my acans healthy. My water perams are really good. They are consistent Salinity 1.025 alk - 9.6 CA - 420 MG - 1410 ph - 8.0 Nitrates 0.0 I test twice a week both no swings since i have been religious about water changes and testing. Lighting i have been using for a year I have LED lighting on a controller. Water temp is 80 all the time. Here are some pics of how they look when they are happy in the tank and here is how they look now. It started to go down hill so I tried to move it to see if location was the issue. Happy... Unhappy Here are how other corals looks in my tank currently.
