I built this canopy in 2 pieces. The rear piece is fixed on the back side of the tank and the front half is hindged so that it swings up and gives you almost full access to the top of the tank. The back side is wide open so heat sould not me a problem. I can get doors built for the front panel for just $20 a door if whoever buys it would want them. I used $100 in the wood and trim alone so this is a good deal.
