Introducing the 2.5 Gallon Aquarium Conversion Kit!

Before placing your order, please ensure that you measure your tank opening to ensure a proper fit. The dimensions of the kit are 5 1/2 inches wide x 11 5/8 inches tall.

This conversion kit provides a fantastic solution for repurposing your 2.5 Gallon tanks.

Please note that the Aquarium Safe silicone needed to seal the sides and attach the kit to the tank is not included in this package. We highly recommend using Aquarium Safe Silicone for optimal results.


This item is eligible for free shipping within the contiguous 48 states.


Installation Instructions:

1. Lay the aquarium with the opening facing upwards.
2. Insert the Conversion Kit into the black rim opening of the tank.
3. Once it is properly set in place, apply a small bead of Aquarium Safe 100% silicone sealant to the outer edges.
4. Use a finger or caulking tool to smooth the silicone.
5. Allow 24-48 hours for the silicone to fully cure.
6. Before housing your animal, ensure that the tank is thoroughly cleaned.
7. Make sure there is no lingering smell of the silicone before introducing your animal to the tank.
8. Always adhere to the directions provided with the silicone sealant.
9. Remember to purchase Aquarium Safe Silicone for this installation.


Please note that the tank is not included with this product.
