How to Reseal a 55 Gallon Fish Tank

소개

Use this guide if your aquarium’s seal is compromised and the aquarium is leaking. You can test to see if your aquarium is leaking.

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. The sealant is prone to wearing down over time, and if you might want to reseal a tank that was sourced secondhand.

Before using this guide, make sure to drain your tank and to thoroughly clean it. 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 take care to not cut into that part and destroy the seams that actually hold the tank together.
