I have made plywood and acrylic tanks(4' x 8' x 16" tall) before. I quit making plywood tanks years ago as acrylic is easier to work with and better suited to aquariums than plywood. Plywood tanks generally have a limited life span unless you do a perfect job and never have rock tumble and hit side of tank, which cracks the resin and then the fun starts!!!
Couple important points for plywood tanks:
-Use Marine Grade Plywood as the glue is waterproof
-Use Stainless Steel screws and pre drill all screw holes
-Food safe fiberglas or epoxy resin is good. use two coats.
-Pigment can be added to the final coat
-Use aquarium silicone in all corner seams. You will need to scuff(with 120 grit sandpaper) the cured epoxy/fibreglas and then clean with isopropyl alcohol so the silicone will stick.
-Curing fibreglas/epoxy fumes are not good to breath. Use a respirator and don't do it in a house.
anymore questions you can pm me.
