[coryjones]

I have been wanting to upgrade to around 300 gallon tank and i came across this plywood tank sounds like a bad idea but seems to work anyone ever seen one of these or built one or have a opinion of this i may try to buil a small one to start?

And didnt really figure out what kind of plywood they are using is it just marine grade plywood?
