OaseBitron C 24 W (UVC Water Clarifier)

I purchased this UV some time ago, and would like to say how easy it is to set up and maintain. The bulbs are also very easy to change .. just press the button on the side of the ballast unit and turn .. this releases the unit from the main cover, pull out and the bulb is very easy to get to. There is a flow setting on top of the unit to allow for the right amount of water to pass over the bulb. I had the older version of this and it was quite difficult to maintain and change bulbs ..this one is so easy. It also keep my water from becoming green with algae particles.
