My suction cups die really quickly and are a pain to replace. Is there a way to hang powerheads onto the tank with some kind of hook? I know a few come with clamps, but I want to be able to hang any powerhead I want.
Just put a magetic shield between the magnet and the powerhead!
Seriously, yes, that can cause problem with some small powerhead... good catch, Danm, but it may work if there is sufficient space between the magnet and the powerhead.
