I obtained the rocks with a fair population of aptasia on them, So I selected the main ones with it after failing to use lemon juice to get rid of them in quarintine. They could retreat too far into the rock. So I put them on the hottest bath water i could with a gallon of bleach. They turned solid white. Then I filled it up again with hot water and put a double dose of dechlorinator in it and let it set for a day. I then rinsed it out with the tap water and dechlorinator repeadly 4 times. Then I let it dry in the sun. So all the aptasia was gone but so was the pink coraline. I guess the maroon just set in first. I then added a small school of peppermint shrimp and a copperband butterfly. I havnt seen any aptasia since. Thanks for all you guys input!
