Anyone finished plywood to what they want then line the inside with plexiglass? I don't know what plexiglass costs but it wouldn't need to be thick and just siliconed together in the corners. Might be cheaper, or atleast a lot easier then sealing it with expensive epoxies

Imo a simple plastic sheet or pond liner would be the easiest route. A standard 36x36" 1/8" sheet of plexi @ my lhs is 25$ so ur talking 8-10 sheets so around 200$.

Even a painters plastic sheets would work, maybe double it up for safety?

Ya. I would even think getting bigger sheets could daventry a bit. I debated a concrete tank but I want to be able to take it down and a wood tank would be easier to build into a wall. I think ill do a plywood tank and see just how cheap it can be done. what's the cheapest 1000+ gal. plywood build anyone has done? Im sure I could get a decent tank for $1500 including lighting, filters, heaters

That's with no quotes or math lol. Still keeping in mind the safety of the fish and my house. Im not going to do a "cheap" build, just an inexpensive one

For 1500 u could get a 500 gal acrylic tank and it will last forever. Check cl for deals or even mfk classifieds

Yes but 500 gal. Isn't 1600. one of the biggest reasons why people build these tanks is for the size. If I plan on keeping a hand full of rays, some gar, shovel nose ect. Id feel better with the tank being 3 times bigger

Price out everything you would need. I don't see how you can do it for $1,500 unless you got awesome deals, buying everything used.
 
filtering will cost 500.00 easy. And wood has been going up in price which does not help.

Expenses add up quick. On my last build, I spent quite a bit of money on repairing/replacing old power tools, a new shopvac, and good 3M respirator mask. Better have some money set aside for the unexpected, like if you have leaks and need to reseal the tank 2 or 3 times.

I wouldn't use acrylic to line a tank. I've thought about years ago, but the numbers don't add up to it make it worth it. Acrylic is expensive. You also might run into problems cementing all the acrylic joints from the interior of the tank. Another thing, acrylic absorbs water and warps, so if it was used as a liner, it might crack. I've build several <200 gallon acrylic tanks.
