DIY Plexiglass Aquarium | Aquarium decorations, Fish tanks and Plants

Plexiglass (acrylic) aquariums have several advantages over glass. They're light and difficult to break, and they provide greater viewing clarity. However, purchasing a commercial aquarium can be expensive. This is why many people build their own. If you do it right, making your own Plexiglass aquarium can be less expensive.

We use only full gauge high quality acrylics in the construction of our aquariums. They are all produced from either Polycast, Plexiglas, or (if larger) Reynolds brand acrylic. These brands of acrylics are widely recognized by reputable aquarium manufacturers and the plastics industry as the highest quality acrylics available. No off-brand imported acrylics allowed. Insist that your investment is produced from a quality product as no other will perform as well in the long run.

When it expands.. if it's right up against your aquarium, it could shatter or crack the aquarium. You need to use material such as Acrylite, or regular standard Acrylic.As far as the waterjet, my understanding and a lot things I have read, claim waterjet cutting is the preferred method of cutting plexiglass. The reason no one on the aquarium forum's use that method is due to cost. I could be wrong but at least thats what at least a handful or so sites have mentioned. I attempted to use a router on some 1" scraps and did not have nearly the same smoothness I did with the waterjet cutting.
