Resource for Aquarium Safe Magnets

[djbetterly]

does anyone have a source for good strong magnets that won't breakdown over time in saltwater?

I've used these in the past, but read some where that even these will breakdown over time and rust out.

I believe there is a sponsor who does a lot with magnets, specifically DIY project focused magnets. I'll see if I can drag up the thread...
