I put together a small tank at home this weekend to play with before I fill up the 275Ga. tank at work Monday. This tank is made from a storage bin, 20"L 14" W X 15" D, and I bent up some 1/2" re bar I had here and stuck in it. It holds about 16Ga. of water. When I filled it, I started with 10Ga. of hot water from the hot water heater tank, then added another 6Ga. of cold tap water. I mixed in 2 cups of Baking Soda into the hot water before adding the cold water, then mixed well. As soon as I put the charger on it, it was bubbling big time. Here are few photos and a couple video links.

3 hours in the tank, a lot of paint floating.
