also, make sure that you aren't popping the bubble algae in the container where the rest of your rock is because you could just spread the spores and it will be everywhere. It's a lot easier to get rid of the aiptasia in a rubbermaid container than in a show tank, so either burn it all off with a butane lighter or use an aiptasia control product. It'll save you some frustration later on... Do your water changes with fresh salt water as said before. If you want to save a little money, just keep the salinity down; the rock wont mind!
