ok so up here in Toronto aquariums cost quite a bit.... that being said, i will give you a example the cheapest tank i can find that would fit my needs is a 180 gallon and it costs 700$ used... now im interested in building a tank out of plywood and im just wondering if it will be more cost efficient to build my own tank or buy a used one? the tank i want to build from plywood would be 315 gallons 7'x3'x2'
