Whats the difference between a sterilizer and a clarifier?
A. As a sterilizer, your Aqua UV system will keep your pond or aquarium water crystal clear in addition, you will have the added benefit of bacterial control which will help keep your fish healthy and happy with less risk of disease. As a clarifier your pond will still have a green tint to it, unless you have 50-75% plant coverage or your pond is in full shade.
