I use aiptasia control(by Blue Life) to keep aiptasia population in check and also for any majanos. I have had sucess by cutting off all powerheads,return pump,anything causing water movement to allow the "juice" to set on the anenome for 2-3 hours. With the aips you just squirt the juice GENTLY on tentacles and they pull it in thinking it's food so they ingest it. With the majanos I completely cover them in the juice and let it sit there. Majanos are pretty easy to remove if you can get to the base good with a knife,screwdriver,etc. and physically remove them. They don't seem to be as messy as the aips when doing it this way.
