Instructions
Go to your local pet store and ask for 100% silicone sealant with zero additives.
Purchase a large tube of the sealant and as a standard-sized caulking gun.
Empty your aquarium and transfer any fish to a temporary tank.
Completely dry off the area to be repaired.
Starting from the top of the crack, lay down a small bead of sealant and drag it along the crack as smoothly as possible.
With a wet finger, gently pat down the sealant so it lays smoothly and has no bumps. Allow the silicone sealant to dry for one day before refilling the aquarium.
