Expired Fluval Epoxy Stick

[DottyClown]

Need advice.

I have an unopened stick of Fluval Epoxy that is way past it’s expiry date. Is it still safe to use? Or will it create havoc in the tank?

Dispose it.

I’m not planning to use it to scape/glue pieces of rocks together. Rather, only to stuff it between crevices of a rock, then make a hole in center of the epoxy to hold a frag plug stem.

So not concern if it cannot bind 2 pcs of rock together. Only concern is if it will contaminate the tank water.

@DottyClown I won't think it will contaminate. Just not sure if the resin properties is still functional. Sometimes it hardens after its shelf life that it will just rendered useless. You can still try if you want.
