UV pond filters are very beneficial to any pond. Understanding how they work will help you provide proper upkeep.

1. Understand What They Do

A UV pond filter is designed to help clarify the water in the pond. This basically means the filter helps to prevent the growth and spread of algae. A pond filled with algae is not only unsightly, but it’s dangerous to the plant and fish life you have in the pond. Algae can smother anything under it. Having a UV filter keeps the pond healthy. A healthy pond is a lovely pond.

2. Use Combined Filters

If you haven’t installed a filter yet, you may want to consider a combination filter. These filters have a UV light component as well as bio filters. These two things work together to make cleaning and filtering the pond a much more efficient process. If you already have a filter, then all you have to do is add the UV and you will have the same benefit. If you don’t want to spend a lot of time trying to get rid of algae then this combination is the best option.

3. Add A Skimmer

Don’t make the filter do all the work. Adding a mechanical pond skimmer will help the filter be more effective. The skimmer will pull debris out that otherwise would be up to the filter to grab. Larger items like leaves and branches can be really bad on a filter. It will make them work a lot harder, and in turn shorten the life expectancy. Leaves and other debris left in a pond can change the eco-balance of the pond, which is not good for plant and fish life either. By removing these items quickly the chances of developing algae or other fish-killing diseases is lessened.

4. Consider Adding Clarifier

Pond clarifier is a biological material that can be added to the pond. This will add healthy bacteria to the water and help to cut down on the growth of algae and other toxins. The clarifier will also help the filter do its job more effectively by giving it less to filter out. It’s recommended that you use a clarifier every spring for general maintenance, at the first sign of problems, and when preparing the pond for new life. You can find clarifiers at any shop that has pond supplies. Just be sure you are picking a quality organic formula to help the pond.

5. Rely on Plants

Plants not only look great in a pond, they serve a purpose. Water plants such as water lettuce and lilies will grow enough to help block some of the sunlight that penetrates the pond. This basically starves the algae as it starts to grow. These plants will also use a lot of the nutrients in the pond to grow, giving your filter less work to do. These plants are surface plants, and won’t require a ton of maintenance.
