The wife and I went to watch a St. Patrick's Day parade at the home of her friend, who lived on the parade route. They had a 120 gallon saltwater tank. Up to that time, I'd only kept fresh water tanks. When her friend's husband turned on the tank to show us, and the VHO super actinics powered up and everything started to glow, I knew I had to have one. That was around 2002.
