Magnets

[CafeReef]

I am going to be printing up a small frag rack tonight, I have a bunch of these magnets at home already for when I do acetone vaper dips on my 3d prints. Could I use these on my frag rack in my tank? I signed up for the Coral Dudes frag of the month club so will only be doing a small rack that will hold up to say 4 coral frags. 10mm glass. Just want to be sure these are safe.

I wouldn't use them in my tank. If I were to put any magnet in my tank, it would be those "rare earth" ones that have the real shiny finish. Even then, I'd give them a good coat of superglue or epoxy on the outsides to keep the metal away from the water. I've considered doing this before myself, but haven't gotten around to it yet.
