But to make an aquarium I'd go with an RTV 100 series silicone. It's industrial strength and much much stronger than ge and will hold up to the water weight of an aquarium.
Thousands of tanks have been built using GE Silicone I. There is a stronger product from GE, SCS1200 series, that would be preferable for larger tanks, and is reputed to be what manufacturers use. A little harder to find, than GE I, but available where the trades shop. Is the RTV 100 not also a GE product?
