Hi All,

I'm at a loss right now and wanted to pick some brains. I received a Greg C Efflo from Battlecorals a little over a month ago. The first two weeks were great, PE was good and even showed a little encrustment until I saw some skin on the tips begin to peel. After monitoring my parameters during this time (Temp 78-79, Alk 7.2-7.5, Cal 400-430, Mag 1450, NO3 17-19, PO4 0.13-0.18) I felt the only thing possibly causing it was LED burn as I'm running my radions at 85% with T5's on my Red Sea 425XL so I lowered down to 70%. This seemed to do the trick temporarily as the peeling stopped only to start back up two weeks later. Again during those two weeks, parameters were roughly the same and after some reading on LED burn, I decided to lower to 50% AB+ schedule. The only other thing that did happen during this time is a favia was killed by a goni as well as a birdsnest that had been STNing (also coral warfare related). I have done a few 15-20% water changes during this time but hadn't run any carbon. Do you think coral warfare could be the cause? LED burn? Anything else? I'm planning on sending in an ATI ICP test tomorrow just to double check things. The bleeding tree next to the Efflo has done nothing but encrust with great PE so I'm just a little confused.

Thanks!

What do your PAR readings indicate? I run a modified EcoTech radiance schedule on my G5s, and it’s set to a schedule of 65%. This us my intensity curve on a Reefer 760XXL using standard RMS tank mounts.

Most of my tank is soft and LPS, and in a range of 50-125 PAR. The handful of SPS that I have is in a 175-250 PAR range.

PAR previously was about 300-350 at the bottom front of the tank. I never took readings where the rack is (front but up 9-12 inches off the bottom).
