What a great idea!!  And certainly easier than finding replacement suction cups.  Thanks for this!

I have found some epoxies deteriorate in the water over time. Have you worked with this particular one before, if so does it hold up over time?

no i have not if it hold for a few months i will be happy the powerheads were falling down daily i think if u let them dry good they will hold they are still holding fine as we speak but only time will tell i will post if they fall or expoxy gives
