I have a huge problem.. I have aptasisa's in the fish only tank. The problem is I have shot most of them with Joes juice and some with kalkwasser..They die but that the tank is to big for me to reach the bottom and back? I cannot get to every aptasia? Has any one every come across this issue and how did you finally get rid of them? I have a puffer in there so I cannot put a peppermint shrimp in there. (well, not long enough anyway) any ideas?
