So been fighting with the dinos last couple weeks. Bottomed out nitrates and phosphate and kaboom! Its been a serious headache. Tried manual removal, turned off the skimmer, feeding heavier to get some nutrients back into the water, heavy zooplankton doses to increase competition, lights out, h2o2, and not much has seamed to slow them down. Im back to running filter socks and cleaning daily to get out what I can. After loosing 2 of my frags and seeing the flesh start to pull back on some others i finally caved today and got a UV filter coming that will hopefully put this all in the past. Luckily the only losses so far are 2 birdsnest frags that have seen tissue loss over 70% of the skeleton. Hopefully i won't have to loose much else in this fight.
