Can you use magnets for attaching things in an aquarium?
Can you use normal magnets in an aquarium? I need them to attach something, and I cannot use silicone since the tank is already filled.
this is only possible if the magnet itself is entirely enclosed in a waterproof shell (plastic), otherwise there will be considerable corrosion (rusting magnet) and possibly subsequent water pollution by heavy metal ions.
