How to Purchase a UV Sterilizer for Aquariums and Ponds

A UV sterilizer is a water filter that uses ultraviolet light to kill bacteria and algae. These sterilizers function in any body of water, including swimming pools, aquariums or ponds.

      Compare low-pressure sterilizers to high-pressure models. Low-pressure sterilizers produce enough wavelengths to kill more organisms than high-pressure models. They tend to last longer and are available in many different styles.

      Match your sterilizer to your problem. Some sterilizers control algae better while others control parasites. Check with manufacturer's recommendations on product boxes to see what the UV sterilizer can control.

      Determine if you need an inline or a hang-on UV sterilizer. Inline UV sterilizers connect directly into the filtration system. Hang-on sterilizers attach to the back of the aquarium. Hang-on sterilizers are easier to use and clean but usually use low-watt bulbs that aren't as effective.

      Determine your need for a UV sterilizer. With proper maintenance and filtering, the average indoor aquarium doesn't need a UV sterilizer. Ponds have a greater tendency to turn green and fill with algae. UV sterilizers can be the answer to those algae problems.
