has anyone tried these yet? I have a butt load I need to get rid of and alot of them are on corals. peppermint are a dud for me and banghia nudis are to expensive. tried kalkwasser paste and Joe's juice and nothing seems to work. I even nuked my rocks with boiling hot water and still have some come back on the rocks.the ones I worry most about is mh plate coral which has one right next to the mouth practically. I just lost a favia so it's starting to really bum me put now.
