Today, is part three of my biggest project yet - building my giant DIY plywood aquarium! In the video, I work on waterproofing the plywood tan with fiberglass and pond shield. The pond shield seals all of the tank to make it waterproof, while the fiberglassing reinforces the seams and corners of the tank. After 2-3 more coats of pond shield, this plywood aquarium will be ready for water!

This is my first time building a plywood aquarium, and I'm bound to make small mistakes along the way. If you're looking for a true "how to" video, I'd look up some of the Fishtubers who have more experience with these builds. I'm confident that this tank will all work out fine, but just wanted to throw out that caveat.
