my problem with physically removing them, is I have extremely pourous rock, and about 80% of the aiptasia I have are inside of the rock a good ways and stick out through the pours, so mechanically removing them is near impossible and if I leave any of them behind they just regrow in a matter of weeks.
If the zapper doesn't work I am gonna bleach my rocks out, put some acid on them and restart the whole system, cause the amount I have is truely annoying
