Breathe Life Into Your Pond If you experience murky water, debris accumulation, or are struggling to maintain a healthy fish population, your pond may be suffering from a lack of oxygen and proper circulation. Air Stone Diffusers - Designed to improve oxygen absorption, these 2-inch diameter air stones create ultra-fine air bubbles that infuse oxygen directly into the water column. Benefits of Increased Oxygen Increased oxygen promotes a healthier and more balanced aquatic environment and supports all aquatic organisms, such as fish and plants. In addition, increasing oxygen improves water quality by reducing the buildup of harmful gases and organic matter, which can lead to stagnation and foul odors. Oxygenation also enhances the nutrient cycle, aiding in the decomposition of organic material and the growth of beneficial bacteria. Aerates Ponds up to 2,000 Gallons, 2 Feet Deep Improves Water Quality & Clarity PondAir 2 & 4 Aeration Kit delivers essential oxygen and circulation to ponds up to 2,000 gallons and up to 2 feet deep. Designed as a complete aeration solution, the PondAir aeration kits contain everything you need to introduce aeration to a small water garden or water feature with a quick and simple installation. Choose between two aeration kit options based on your pond size, and start aerating the water in your pond today. Design For 24−7 Use Easy to Install & Maintain Quiet Operation & Energy Efficient High Efficiency, Quiet Aeration Pump These whisper-quiet diaphragm aeration pumps are the heart and soul of our the PondAir 2 & 4 Aeration Kits. Costing just pennies a month to run, you can feel good about providing constant aeration to your pond. Airflow Control Dial Dial-in aeration output with the twist of your finger. The airflow control dial enables you to restrict airflow to your pond when desired without the need for tools or stone adjustments. Simply turn the dial to restrict airflow or run the aeration pump at full output for maximum aeration. Black Vinyl Airline Flexible black vinyl airline allows for strategic air stone placement to maximize air and water circulation. PondAir vinyl airline has an approximate inside diameter of 1/8-inch and is packaged in 30-foot rolls. Directional Check Valves Water tends to climb aeration airlines when your aeration pump is powered down. Airflow check valves allow oxygen to travel outwards from the aeration pump while preventing water from traveling into the lines when not in use to prevent potential water damage to your aeration unit.

Although waterfalls and fountain sprays add oxygen to the water, they are not always enough and should be supplemented with diffused aeration. With bottom-diffused aeration, water is more efficiently circulated, which increases dissolved oxygen levels. Bottom-diffused aeration: Reduces Maintenance – In conjunction with proper filtration, adding aeration will keep your pond cleaner longer. This means you can spend more time relaxing around your pond rather than spending time cleaning it.Saves Money – Aeration systems are energy-efficient and can help you cut down on your energy bill. These systems are designed to run 24/7, yet only cost a few bucks per month. Rather than running a costly waterfall pump all the time, use a pump only when you are there to enjoy it and rely on a properly sized aeration system to keep the dissolved oxygen levels high. This small change can save you hundreds of dollars each year.Supports Beneficial Bacteria: Beneficial bacteria are aerobic and need oxygen to survive. These bacteria consume the excess nutrients in your pond, which fuel algae growth and pond muck accumulation. Aeration allows these bacteria to work harder to clean up your pond, leading to an overall cleaner pond. In addition, fish love aeration! Your fish will gather around and enjoy the bubbles coming from the diffusers. FAQs How do I choose the right size aeration kit? When it comes to aeration kits, finding the right fit is key. Properly sized aeration units will infuse oxygen into the pond, circulate water, and help create a balanced ecosystem. Your fish will be happier and healthier, and you will have reduced excess organic material in your pond – meaning fewer nutrients to fuel algae growth. When selecting an aeration kit, you need to account for pond shape, depth, and shape. How often do you need to replace the air stones? You only need to replace airstones if there is damage. If you are experiencing poor performance and low amounts of air coming out of the blue air stone, start by cleaning off any debris or algae that may have accumulated. If cleaning does not improve performance, then most likely the unit needs a compressor maintenance kit. How often should I install a new maintenance kit? We recommend installing a new maintenance kit every year. Over time the compressor diaphragm can become worn, and this wear will greatly reduce the air output of the unit. Installation is easy and there are step-by-step videos of the process. Will a pond aerator keep an open hole in the ice during winter? Aeration kits infuse oxygen into the water by releasing small bubbles from an air stone, which moves the water and allows for gas exchange. In most climates, aeration is sufficient to maintain open water in even freezing conditions. If you live in a colder climate, however, your water garden may need a little extra help during the winter. In this case, a combination de-icer and aeration kit is a great solution. Using them together will ensure that a hole is kept open in the ice, water circulates properly, and dissolved oxygen levels remain high. Additionally, using a pond aeration kit during winter will allow you to use a smaller wattage de-icer, which could help you save money on your energy bill. Are there other steps needed for winter pond care? During the winter, we recommend moving the air stones to half your maximum depth. This will help reduce ice formation and keep a pocket of warm water for your fish at the bottom of the pond. Maintain a Thriving Pond Ecosystem Keep your pond healthy with energy-efficient aeration year round.
