the tank is 160g made from 3/4 plywood and will have a epoxy coating on the inside. Ill go buy the epxy tomorrow and in a couple of day be able to install the acrylic view window. I was able to get the acrylic from a guy on craigslist for 100.00 its 6'X4' enough for the viewing window and the top. I'll build a sump out of the same material cause I have some left over, was going to use my 55g but now I'll just sell it
If you think trying to contain a hundred plus gallons of water in a plywood box is scary, just think about trying to contain it in a glass box! It's all in how you look at it, isn't it? Tell the wife, "I'm going to make a six foot long glass box, set it on a table in the living room and fill it with water." But, first hide the rolling pin!
