F Aiptasia used, there were a LOT more than I anticipated, I mean I know I feed a good amount, but damn. A few days later the white parts where I squirted the stuff is still there, so that's good it's probably some mixture of kalk paste and glue of some sort. Either way though I may have to think about biological control methods, because if I get 95% of them, those 5% will just fill the void left by them. Then what if I miss one on the side of the walls where I can't see, or in some plumbing... god I hate aiptasia.
