UV Sterilizers can be a vital piece of equipment when it comes to successful Reef Keeping. These devices draw water in by means of a feed pump. As they do the water is pushed through a tube inside, along a UV Light, where it helps rid a tank of disease causing micro-organisms and even algae spores. The result is a tank that is more likely to have healthy fish, corals, clams and other inhabitants. Added benefits of UV Sterilizers is they can also potentially raise redox levels in aquariums, greatly increasing water quality and clarity.
