96 hour mark and it's starting to look like it's taking it home. I'll probably leave it run another day, but the xenia is starting to come off the rocks sporadically so I'm turning the pumps off every so often and grabbing any that look loose. So far the only thing I've lost is a small devils hand. I was thinking a kenya tree and sinularia wouldn't make it, but they look like they're hanging in there.
I left the treatment in the tank for 5 days: 2 days longer than recommended, but necessary ,so I wasn't sure what to expect for collateral damage, I was very pleasantly surprised. I have 70 astrea snails, 20 nassarious, 3 emeralds, 70 blue legs, a serpent star, 2 tuxedo urchins and a few frogspawn, duncans, trumpets, favia, pectinia, shrooms, zoas, palys, sinularia, kenya tree, acan, blastos. The only casualty I suffered was a devils hand. Unfortunately my GSP survived in style. All CUC were unharmed. I did not do a water change yet as to leave some of the medication in circulation to finish off any stranglers, but I fired up the skimmer and loaded the reactor with carbon and purigen to pull out the organics from all the deceased xenia. I thought I was going to have to break down the tank, so I am stoked this worked out so well. Hope this was helpful.
