resin for DIY magnetic algae glass cleaner

[astroboy]

Hello,

 

I"m making a a magnetic algae class cleaner using some cheap and powerful rare earth magnets. I want to seal the part that will be in the aquarium with some sort of resin or epoxy so that the magnets don't corrode in the tank. Does anyone have an recommendations as to what a good resin or epoxy might be?

 

Thanks,

 

Mark

Would aquarium safe silicone work?
