i saw this video 1000gal fish tank aquarium DIY - YouTube and i want to know if this well work? the video say the size of the tank is 8'x4'x4' fish tank made from plywood 2 by 4's and acrylic
I've seen quite a few build threads for plywood tanks but, I've seen just as many either end up leaking or the plywood ending up bowing out. I've thought about it in the past but, I won't risk 1000g of water on my floor.
You have to use some thing like pond coat to make it water tight. Must make sure that water can not come in contact with the wood at all or it will leak someday.
