Aqueon Silicone Sealant

Aqueon Silicone Sealant is a 100% silicone aquarium sealant that stops leaks and forms a permanent, water-tight seal. It is the same high-strength silicone used to build new aquariums, so it bonds glass securely and stays permanently flexible, it will not crack or shrink over time. Non-toxic once cured, it is safe for both freshwater and saltwater tanks. Browse more aquarium tools and maintenance supplies at Squeaky's Aquatics.

Features

• Stops leaks: a waterproof seal reseals seams and stops leaks fast.
• Permanently flexible: will not crack or shrink, so the repair lasts.
• Aquarium-grade strength: the same silicone used to manufacture new aquariums.
• Non-toxic: aquarium-safe once fully cured, for freshwater and saltwater.
• Two colors: clear blends into any tank, black gives a clean, hidden-seam look.

How to Apply

1. Drain the tank and let the repair area dry completely. Scrape off old silicone, algae and residue.
2. Apply a continuous bead along the seam or crack, then smooth it with a wet fingertip or tool.
3. Let it cure fully before adding water. Allow at least 24 to 48 hours for a complete cure.
4. Rinse the tank before returning fish, plants or corals.
