Drain the tank, full it with beer, and pee in it too A serious answer would be to put a powerhead pointed at the anemones that are in the crevices so they will move out because too much flow and then you can remove them easierHow about someone tell me how to murder all my rose bubble tip anemones? I can't get rid of them and they keep multiplying in my 300G SPS reef. Hard to reach them deep down and on back wall crevices.
