I had an aptasia problem it was on some LR I was given and i used Joe's Juice! Worked great! When I got it to a controllable stage like there were a few smaller ones in the hard to reach cracks and crevasses I bought a pair of peppermint shrimp and i haven't seen one since!!!!! The shrimp do a great job I havent seen aptasia in months, was worried they might starve due to lack of aptasia but mine love flake food they are very interesting creatures they've got personality and they constantly are battling it out with my coral banded shrimp, makes me laugh!!!! Good Luck!
