I want replace the suction cups that hold filter outlets, thermometer probes etc. in place with magnets. This is for my FW tanks, I am tired of suction cups not working.

Does anyone know where I can find these?

I'm interested in knowing this as well. Would this be possible for saltwater tanks as well?

You could always coat a regular magnet in sealer.
