Juwel Aquarium Silicone Black is used to fix Decorative Backgrounds to the back glass panel or to fix the Juwel Filter Systems into your Juwel aquarium.
This silicone has been designed especially for the use inside the aquarium.
Take care to ensure that the surfaces to be cemented are absolutely clean and dry before applying the silicon.
A dry skin forms on the surface of the silicone after just a few minutes. The silicone is firm after approximately 1 hour. Wait 24 hours before filling the aquarium with water as only then will the silicone be fully hardened.
