Geocel Aquarium sealant is a silicone dealant ideal for aquaria building, mounting valves and sealing connections.
It gives a permanently flexible, watertight seal and excellent adhesion even under extreme pressure.
This aquarium silicone can be used for constructing aquaria and fish tanks in glass with or without metal frames. It is ideal for repairing existing aquaria where non-silicone materials have broken down or failed and can also be used for applying fixtures inside or outside the tank, mounting valves and sealing.
The sealant will form a tough, water tight rubber seal, harmless to fresh and salt water fish.
Must be left for at least 48 hours before adding water.
