I have TONS of epoxy experience but was worried about it in the tank long term. I'm talking about your regular epoxy (liquid 2-part) not the marine putty we use for rocks. I wonder what the toxicity of it would be.
I have some pretty AWESOME Nimble Nano Magnets that are embedded in acrylic that would also work for this. I contacted the guy who makes Nimble Nano's and asked him about making me some of these. If I had experience with acrylic I would try it this weekend
