It's an unnecessary expense, in my opinion, and the bulbs need to be replaced annually (at least). If your tank's doing well, don't spend the extra cash. If your tank's not doing well, look for the cause of the issue. Technology is neat, but it won't necessarily compensate for an "out-of-balance" system. Easiest solution to algae is to play with light levels and duration of daily lighting. A simple $10 light timer will help that.
I don't believe I need
a UV filter and I know there are a million other ways to prevent algae problems. I just wondered how it would work if I picked up one of them. I don't really have that much of an algae problem either. I have a small amount of free floating green algae, but nothing my water changes don't take care of. I already have a timer as well so my lights are already controlled. I was just looking for new products to help my tank better, but you did bring up a valid point in having to change the bulb. Can you even buy UVC bulbs anywhere? It does seem like it would be an unnecessary expense.
