Help... any ideas? My corals on this one rock look horrible. I have LPS, some easier SPS, zoas and RBTAs throughout the tank that look great and are growing. As stuff has been growing in the 75 (>6 months since the upgrade from the 29) it took a little while to get the Alk/Ca dialed in but the parameters have stayed pretty good and other coral has thrived. Can anyone tell by looking what the issue may be? The LPS piece (looks like a giant acan I forget what it's called) I know should be on the sand but it was glued into place a long time ago and had been doing okay.
