Probably 6 mos ago I bought live rock with a nice colony of yellow star polyps. After @ 2 days tiny little aptasia started popping up all over the live rock...... I used Kaulk over a period of weeks until I got rid of all of them..... I thought.... I hadn't seen any in months and all of a sudden they started popping up again. They are small but they are locating themselves right in the middle of my other corals, etc. Several are very close to the star polyps and one is right in the middle of a colony of eagle eye zoas. I hate to use the Kaulk so close, I know that, aptasia or whatever, the Kaulk will kill whatever it lands on. I tried boiling water but that didn't work..... I'm guessing it cooled off too much before I got them squirted.... and I did hurry..... Anyway, I'm stumped. Anyone have any ideas?
