Was searching the web today and i came across alot of people who made there reef tanks out of plywood. No not the stand the actual tank . does anyone on MR have a tank like this. I would post some that i saw but they are on other sites and im not sure of rules on that. INCREDIBLE. i saw that it could get pricey if it not a 400gallon tank but cool none the less

The Fresh water guys have been doing this for years. Ive seen big tanks 1,000+ gallons made of plywood. They are surprisingly strong. Generally they either epoxy the wood interior or cover all the interior surfaces with fiberglass. Ive even seen some made using a pond liner on the inside. Its a great way to get a huge tank pretty cheaply.
