recently got this zoa rock and the power head seems to be too much flow for the zoa? I didn’t have a problem for the first week now it flops all over and looks like it’s hardly staying on. I’ve had a few polps fall off the rock and I don’t have glue to put them back. Tried to glue them tk a dry rock but the superglue I had wouldn’t hold. Not sure what to do and how to make sure I don’t lose a good cluster of polyps. Please help.
