This worked fine for me. I installed a reverse osmosis system in my 8 x 16 orchid greenhouse. I already had an aquarium this size, but I found that I didn't have enough water. Install it so that the outlet is at the top! I read someone's review and it installed upside down. Ignore the label if it's upside down. Make sure you have the correct air pressure when the tank is empty - buy a low pressure gauge for this measurement. The pressure is too high and water is not filling the tank. Too low and water will remain in the tank. Don't try to guess what it should be with water in the tank. The first came dented, it was immediately replaced. I am very happy with it. I don't remember, maybe I bought the hardware for the top separately. I use ยผ" fittings and tubing in my system. I also use black tubing to prevent algae growth. Let's see how they hold up in the sun.
