I am building this unit into the supply manifold for the new system. It will have two 65 watt UV bulbs and run on emperor aquatic ballasts.
It will be very similar in design to this unit but instead of a U shape vessel it will be a more linear design. http://goldfishgarage.blogspot.com/2011/02/diy-130-watts-2-x-65-watts-uv.html
