My impression was that it was a brown jellly infection and the infection itself was spreading to other similar LPS corals. Other stuff, shrooms, zoo's, a sarcophyton,,, looked ok but a bit stressed, possibly from the die off happening, possibly because Jared's salinity was way high since he was a day or two behind in top offs and his hydrometer was off by about .008 compared to my calibrated refractometer.
I brought Jared some fresh RO water so he could mix it and do the water change. We pulled the affected LPS frags and started a canister filter with carbon while I was there. When I left he was starting to bring the salinity back down.
Jared,
Randy replied to my question, the high salinity could easily explain the over the top Ca reading, and hard water top off could also be adding to the Ca level. Let me know when you get the salinity down to about 1.020 on your hydrometer and I can stop over again and we can check everything again.
