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.

tim, proublem is that the acrylick locally is $12 a sqft for 1/4 material, so for a 7x3 and 16 inch tall tank, that sould be lots of $$, and the acrylick needs support as well, so for wood, there is not much to save on
