they have a uv hob with surface skimmer made by aquatop. its on the true aqua web site. $50-$59 depending on size. its adjustable too, i think it has 5 step filteration. the uv light has its own switch ,so you can run it for a few hrs not all day. this extends bulb life. from what i understand, you want to run it on low,so it comes into contact with the water longer. pretty soon all hobs will be this way. hopefully.
