FS: 4 foot tank with wood stand and canopy $50 (Richmond)
 

The tank is 4 feet wide, 1 feet from front to back, and 16.5 inches tall. As for how many gallons? your guess is as good as mine.

As you can see from the below pictures, it was used as a salt tank and it includes the coral, shells, and a powerhead. There are a few other stuff that I'm going to throw in such as a HOB heater, air pump, and hydrometer. These items are being sold as is. It's not mine and I'm selling it for a friend hence the cheap price. It holds water as you can see. First $50 takes it.
