Underwater decor

[joshua1316]

Hi, not sure if this is the correct section but I have made some custom decor for my tank and want to seal it so nothing leaches out of it. What would be good to Use? I've seen epoxy resin would be good but also heard it's not ment to be underwater. Any recommendations?

I've used 2 part expoxy to seal a foam rock wall I built. Its non toxic an lasted a few years until I broke the tank down. One thing is it may yellow over time.
