How to coat something to make it fishy safe.

Thanks for the replies everyone. I received an annoyingly ambiguous response from Design Toscano:

[FONT=&quot]Thank you for contacting customer service with your inquiry. We don't recommend using the rain gutter in a fish pond as it's not designed for that use. This item is non-toxic. [/FONT]

Okay, so it's non-toxic. That's a good thing. But what is this "not designed for that use" stuff? We use all sorts of things in our aquariums (lighting grids, PVC pipes, flower pots, etc) that are not designed for that use. It doesn't make them unsafe.

Anyway, can anyone tell me more about this marine epoxy? It sounds like that might be what I'm looking for.

And for the record I'm not going to subject fish, whether they're ornamental or feeder, to experiments.
 
"not designed for that use" is their cover their butt statement...just like many sealants say not for use in aquariums, it protects them from liability.
 
Most epoxy is very durable, and once cured is inert. The only thing I'd worry about is UV damage breaking it down, probably not an issue in an inside tank (an outdoor pond...different story). If you're very nervous they make 'potable' versions (for contact with drinking water) but they're more expensive.

At your local hardware store there will be a 'dual syringe' type package...you push the plunger & it dispenses equal parts resin & hardener.

Just make sure you mix the resin & hardener reeeeeeeally well, or it won't properly cure.
