I bought a used 55 gallon aquarium today, and some of the silicone sealer on one side is peeling off. When I was at Lowe's the other day, I grabbed a silicone that I thought I had read would be good for use inside and outside an aquarium: GE Premium Waterproof Silicone.

Does anyone have experience with this type? I am not sure I need it inside the tank, but if I do, would this one be safe?

I would really appreciate any information from anyone who has been there, done that.
