Stored chemicals

[MadReefer]

SO in my effortless pursuit to find the epoxy I found other stuff but not sure if they are still good. Can anyone advise.

Revive - opened and stored in the attic for about 4 years

Kalkwasser - opened and stored in attic for about 4 years

GFO - stored in he house, not attic

Thanks

Kalk and gfo should be good, I would toss the revive

Thanks Art.

I don't have reactors anymore so anyone want half a jar of Kalkwasser?

Agree. I believe Revive only good for 1 year
