Sad to hear about your anemone. I normally only place nems in lower flow tanks or in an anemone box well away from any power heads. Even then it’s not fool proof.Bad news, the Green Bubble Tip Anemone seemed to have found a solid spot towards the lower part of my tank touching the sand, between two rocks. I left the gyres on at 25%, and this morning I came to a cloudy tank and completely dead BTA. Pretty upset, already cleaned it up and preparing for a 20% water change. Thankfully I already have blue chemi pure running, ordering a couple more just to be safe (chemipure). The new tangs appear to be doing well and look amazing. I think I'll hold off on any further anemone for quite sometime. Shame, it looked really beautiful.
