30% water change was done on Saturday and chemipure elite is back in the overflow above the diy scrubber. No signs of any kind of algae except for a little film on the glass. All corals are ok except for one chalice that was on its way out anyway and all livestock seems fine except for the emerald crabs which I have not seen in a couple of weeks. I saw a claw though, and while that could be from an older crab that I know for sure died I think it’s most likely that neither emerald is with me anymore. For the moment the only real issue is Aiptasia. I’m going to try and take some out with F-Aiptasia again and see if it works better this time. There are a couple of them in places near corals that I really want to go away so it’s worth one more try. I wish the Berghia Nudibranchs had been bigger and more effective. By now I’m sure they are gone.
