I have a mat of zoos. There is no hard rock attatched to it. It is just like a mat of zoos with some mud underneath them. How can i attatch them permenantly to a rock?
Gel super glue works the best for me. U can glue under water kinda doesn't seem to stick as well. Remember that all super glues create heat when they cure. Have a bowl of reef water handy and dip the zoo's in after a few seconds of the gel hardening.
