Introduction
Use this guide if your aquarium’s seal is compromised and the aquarium is leaking. You can [link|https://www.firsttankguide.net/leak-test.php|test|new_window=true] to see if your aquarium is leaking. [br]
The silicone sealant is present on the inside seam of the tank on all corners, the bottom, and it holds the panes of glass together themselves. When the sealant is compromised, the tank’s water will leak out and endanger the fish and critters in it.

Before using this guide, make sure to drain your tank and to thoroughly [link|https://cafishvet.com/fish-tanks/how-to-clean-a-fish-tank/|clean it|new_window=true]. You will also need to make sure that the silicone you use to reseal the tank is fish safe, being nontoxic and suitable for constant submersion in fresh or saltwater. Consider wearing gloves and being in a well ventilated area when using the silicone. Remember that new silicone will not adhere to old silicone, and for that reason it is important to be diligent in removing the old silicone. Be sure to be careful and go slow when using the blades to cut out the old silicone, you’re at risk to cut yourself! And as stated earlier, silicone is also holding the panes of glass together, so you also should take care to not cut into that and destroy the seams that actually hold the tank together.
