How to Remove Aquarium Sealant

Aquarium sealant is a solid, adhesive rubbery gel composed primarily of silicone. It is extremely strong and used to bond heavy sheets of glass together in most aquariums. Along with strength, it's also known for its durability, for it can handle years of abuse and continue to hold glass together despite corrosion by both fresh and saltwater. However, if the situation calls for it, for example taking apart an aquarium, it can be removed quite easily.
