DIY Fiberglass Tanks

Updated April 17, 2017

Making your own fibreglass tank is a simple task that doesn't take much time to complete. It can save you money, and once completed the tank can be used for all kinds of hobby purpose, from a home for your pet fish to a giant terrarium.

Measure the size of tank you wish to make. Have the fibreglass cut to size in the store where you purchase the fibreglass. This will minimise risk of cracking the fibreglass. You will need five pieces, one for each wall and one for the bottom.

Take two connecting walls of fibreglass. Apply glue to the edge of one wall and then stick the other wall to it. Do the same with the other two walls of fibreglass. You should now have two L-shaped fibreglass structures. Let dry completely.

Attach the two L-structures with glue and let dry. When they are dry apply glue all along the bottom of your structure and place it on top of the bottom piece of fibreglass. Let dry.

Apply waterproof corking to the outside and inside edges of your tank to ensure that it is airtight and resilient. When dry you are ready to use it.
