Lost everything in the move…..have had rocks sitting in Clorox for 20 hours and the GHA is still there….white, but is not releasing with a slight tug. AND my delicate Zoas that close at the touch from a scarlet skunk cleaner are hanging on too. Haven’t turned white, staying gray and extended but won’t release. So. Fellow reefers what is it really going to take to kill off GHA?
