Magnetic rock structures

[CasperOe]

Hi Reefers,

I am looking for some more real estate- and possibly hiding places for some of my fishies.

During one of many trips around the deep, dark internet I came across pre-made structures (shelves, caves etc) with magnetic attachments for the glass, back wall and so on.

Does anyone have experience with any such items- and where did you get them from?

Thanks

Iron magnets will rust in seawater, I'm not sure about rare earth magnets. Even encapsulated magnets can fail - they are often used in "algae scrubbers" and it is pretty common to see those split from expanding rust.
