It is a "chip" board but is moisture resistant and guaranteed to be so. That being said.....You will have a barrier(epoxy) between is and the water. Nothing to leach if the barrier is properly applied. The initial wood is unattractive but will be covered. The outside is covered too. Since the water is inside, moisture shouldn't be much of a concern but each wood wall should be double ply, opposite joined,screwed and glued. The exterior wall needs to be any kind of exterior (OXB) type wood. Smooth "x" wood can be found no,sweat. We are talking$55-65.00 a sheet for the wood alone. Good luck. This is a plan of mine too but,I will be doing a 700-900gallon with a 100gallon drop off. Good luck!

Please do not follow this advice! OSB is not an appropriate material for a plywood aquarium. OSB is cheap and has a great deal of shear strength along the plane of the board, but not much bend strength. This is why it is used as exterior building sheeting and not flooring. Plywood can withstand a great deal of pressure.
