Source for reef safe magnets?

19Mateo83 · Mar 10, 2023

I would like to be able to use magnets to attach certain corals to the walls of my tank. Is there a source for reef safe encapsulated magnets? I have looked all over the place and I can’t t find anything.

Check out KJ Magnetics. Some people here order from them to use on the w, and will use cheaper magnets from Amazon on the dry side.

There are a few others, but here’s a thread I had saved talking about them:

It should be noted that K&J sells mostly (all?) neodymium magnets. If you've never played with them before, they're considerably stronger than you'd expect. Don't oversize the magnet and it'll be easier to hold on to. If it slips out of your hand (towards the other magnet), it could easily shatter the glass. For that reason, I'd make sure to get rubber coated magnets for the wet and dry side (which I assume you'd be doing anyway), to lessen the chance of that happening *when* you do lose your grip on one.

Something else to think about. As difficult as it is to pull the magnets apart, I think they'll still be able to rotate relative to each other. Meaning, you might want to either use two individual magnets on each side or place the magnet on the coral in such a way that it isn't top heavy otherwise I'd be concerned it rotate itself to it was hanging upside down from the magnet.

I will definitely have to use coated magnets for both sides of the glass, my nano has a built in filter in the back. I’m actually counting on the strength of the neodymium. The smaller and less noticeable the magnet the better in my case. I have encapsulated them myself in the past with purple epoxy stick and not had any problems but I want them to disappear into the black background and look make a Monti. Cap. Look like it’s growing out of the wall.

Don't use rubberized magnets, they are not sealed. Only plastic from k&j.

10-4 on the plastic coated from k&j

In case you are looking for a mounting solution, check out the new CoralWall system : )

I also sell epoxy coated magnets, further encased in clear acrylic that are guaranteed not to leak: https://reefeco.com/pages/our-magnets
