Hey Lou,
The tank is only a 38 gal. the total system will have around 80 gal. I know this probably seems a little much for a 38 gal, but all the equipment I built will not fit under a stand. My wife also wanted the tank to look like it was built in to the wall. I also wanted very easy access to all parts. I hate being cramped for space. I wanted to go bigger but when I started to add up the cost of a bigger tank to do it the way I want to do it cost rose sharply. I also took into account my monthly electricity bill. When finally taking this all into account I decided to stay with a smaller tank.
The stand is wood I built it earlier, its painted.
