Mold Resistance Silicone to Seal Aquarium Stand

[Yellow Eyes]

I know silicones that contain mold and mildew inhibitors are bad to use in the aquarium. What about outside of the aquarium?

I am building an aquarium stand and I wanted to seal up all the cracks in the sump area, both the floor and the bracing above to prevent water or humid air penetration leading to eventual rot.

I will also add that I am probably 1-2 months from getting the aquarium up and running.

Id say if you are only sealing the inside/outside of the stand and allow it to cure it would be fine.

I should also add that it’s paintable and I plan on adding a few coats of primer and likely an appliance epoxy paint on top of all this.

sounds like a good plan!
