I am transitioning from a 72 gallon bowfront to a 110 with a basement sump. The 110 tank stand and canopy was purchased from another member. Since tank is empty I wanted to seal the inside of the canopy. Can any suggest a sealant for wood canopies? Thanks. A fellow MASC member is coming over to start the plumbing tomorrow. I will take plenty of pics and post updates as thing progress.
