Things You'll Need
- Flat razor
- Cotton swabs
- Rubbing alcohol
- 1 tube silicone
- Disposable rag
Instructions
Remove any existing silicone from the edges and corners. New silicone will not adhere properly to an existing coat of sealant, so it's important to apply the silicone to a "clean slate." Use a flat razor to free any hard-to-remove beads of silicone, scraping from the edges toward the center.
Clean the corners of the aquarium with cotton swabs soaked in rubbing alcohol. Allow the alcohol to evaporate thoroughly.
Snip off the nozzle plug of a tube of silicone with a pair of scissors. Open the nozzle to a diameter of approximately 3/10ths of an inch.
Hold the nozzle of the silicone tube in the corner of the aquarium. Draw the nozzle along the edge while squeezing the tube, applying a thin bead of silicone.
Pull your finger lightly across the silicone, molding the silicone into the corner and removing any excess sealant. Wipe the extra sealant onto a clean, disposable rag.
Place the tank in a dry, ventilated area, and allow it to dry and cure for at least 48 hours before use. Wash your hands thoroughly to remove any silicone residue.
