It appears that the fandangly new idea is to use magnetic mounts for power heads or wave makers instead of suction cups. Is this because when the cup fails (as it always does, with time) there's catastrophic problems?
If so, why can't I find a good DIY for replacing existing suction cup mounts...
Does anyone know where I can rent some of these?
I don't want to buy 6 sets to sit around collecting dust after my tank move.
I appreciate any advice.
