I have an old power head from my first SW tank that I was going to use to cure some rock. I don't remember the brand of the powerhead or where I got it from. The blades on the impeller are fine but the magnet and the piece with the blades have come apart. I've tried super glue, silicone and PVC glue and none of them seem to hold after I start up the powerhead and put it in water. Anyone have any suggestions?
