Well out of the 2 unknown sps frags, 1 is stning. The smooth skin acro seems fine. I have no idea why stn is still affecting my sps. Carbon dosing has been stopped for multiple weeks now and I haven't changed anything. Oh well, keep on trucking right?!! Lol. Hopefully since the acros I have coming next week are local, home grown and not fresh cuts, I'm crossing my fingers that they'll be more tolerant to my system. Lps (blue ridge coral) is growing like mad on my overflow so lps is super happy. Xenia and aiptasia are happily popping up everywhere too, but they can just about survive anything.
