Aptaisia removal

[1bigfish]

Thanks for the replies everyone. I have tried injecting with lemon juice, hot water. A lot of the aptaisia are smaller, they just scoot into the Rock and I can't get them.

I bought some new rock and have resorted to pulling the aptaisia Rock. I put it in a bin and I put boiling fresh water on it. Hope that will kill everything. Down side all the good stuff is dead to.

Has anyone tried boiling fresh water and had success with getting rid of aptaisia?
