The Proven Solution in Water Garden Treatments Natural. Clear Water. Guaranteed. 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. 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. CrystalClear KoiAir Aeration Kits are the ideal choice for aerating medium and large water gardens and koi ponds. A powerful yet energy-efficient dual diaphragm SilentAir Aeration Pump infuses your pond with fresh air while the virtual maintenance-free membrane diffuser plate allows for maximum oxygen uptake. Choose between three aeration kit options based on your pond size and start aerating the water in your pond today. High Efficiency Aeration Pump: Running on as little as 17 watts, these whisper-quiet SilentAir aeration pumps are the heart and soul of our KoiAir aeration units. Diffuser Plate Assembly: Each KoiAir diffuser plate utilizes a sturdy base plate and incorporates a 3/8” barbed inlet for quick hook-up. PTFE Non-Stick 6" Membrane Diffuser Stick: Virtually maintenance-free, membrane diffuser sticks resist clogging. Membrane sticks have the same effect as air stones without the maintenance. Self-Weighted Airline: Heavy-duty flexible airline designed to sink the pond’s bottom even when filled with air. EasySet airline is extremely resistant to cuts, snags and kinks. Aeration promotes oxygen which is the lifeline of every ecosystem. 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: In addition, fish love aeration! Your fish will gather around and enjoy the bubbles coming from the diffusers. 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 diffuser stick? You only need to replace the diffuser if there is damage. If you are experiencing poor performance and low amounts of air coming out of the stick, 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. Can my fish get hurt by the diffuser plates or sticks? Our specially designed diffuser plates have curved/rounded edges with no sharp corners. Also, our PTFE diffuser sticks are cylindrical and smooth, with nothing sticking out that could injure your fish. How often should I install a new maintenance kit? We recommend installing a new maintenance kit every year. Over time the compressor diaphragm(s) 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 a diffuser stick, 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 diffuser sticks 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. Can this unit be placed directly pondside? Yes, it is recommended to place the KoiAir unit pondside out of direct sunlight while also ensuring the compressor has proper ventilation. Energy-efficient aeration improves your water quality, so you can get back to enjoying your pond!
