Can I have these in my tank with no ill effects on anything?

Thanks reef friends!

No. Ceramic magnets still contain iron. They have to to be magnetic. The only safe magnets are those that are encased in epoxy, or some other inert sealant.

Thank you Evil :)

Here's a link for how they make them if anyone is confused in the future:

NO to ceramic/ ferrite magnets.

I was making one of the little seaweed feeders like on BRS. With the mesh and whatnot for my tang trio :)
