So I'm going to start with giving a little context to what I have going on. I have a 60 gallon display with a Kessil ap9x over it and a 20 gallon sump then I have a 17 gallon frag tank on the opposite side of the wall in the garage with a 10 gallon sump from that that returns back to the sump in the house. The whole system is tied together with the same water. And the frag tank in the garage is a 8 in deep tank with the frag rack sitting 3 in from the bottom so roughly 4 inches of water with the same light as I do in the main display over it
So on seven separate occasions I have taken corals that were starting to bleach out or die from the display and put it in that frag rack and they would bounce back at a very rapid rate. I have even received corals where the bag had drained all the water out half the flag would be dead and put it in that rack and they grow back. And at a crazy fast rate. So last week I take three acrofags out of the frag tank that had polyps extended for at least a few months throughout the day and they looked beautiful and put them in the display which is the same water and they close up and never extend eventually start to bleach and I pop them off and put them back in the frag tank. I've put a par meter on it and they are relatively close in their numbers plus or minus 50 par but mostly minus. What am I missing here? My display seems to be the place to send corals to die. They do have direct flow in the display as opposed to simple movement in the frag tank. Maybe that's it I don't know I'm at a loss
