CrystalClear PondAir 4 Aeration Kit for Small Ponds & Water Gardens, Improve Water Oxygenation

CrystalClear PondAir 4 Aeration Kits are ideal for decorative ponds and water gardens of up to 2,000 gallons with a maximum depth of two feet. Powered by highly efficient diaphragm compressors, CrystalClear PondAir Aeration Kits infuse your pond with vital oxygen while remaining whisper-quiet and cost-effective. An airflow control valve on the top of the pond aerator lets you adjust the aeration output to your pond with the simple turn of a dial. If you experience murky water, debris accumulation, or struggle to maintain a healthy fish population, your pond may lack oxygen and proper circulation. As water temperatures rise and debris accumulates, the available oxygen in your pond’s water plummets. CrystalClear PondAir aeration kits are perfect for aerating water gardens and koi ponds to ensure sufficient circulation and oxygen is available throughout the pond. This koi pond aerator creates an environment suitable for aerobic natural bacteria to flourish and continuously clean your pond water. Aquatic plants will thrive, water quality will improve, and you will reduce muck, algae, and foul odors. Choose between two aeration kit options based on your pond size. Each kit includes a diaphragm compressor with a six-foot power cord, two bubbler airstones, and flexible vinyl air tubing. Powered by a 115-volt compressor with a standard plug for household outlets. FAQs  How do I choose the right size aeration kit?  Finding the correct fit is essential for a functional aeration kit. Start by measuring your pond’s length, width, and depth in feet, and note the shape. With these dimensions and figures in hand, contact one of our experienced Pond Coaches for precise advice on selecting an aerator. Alternatively, follow the appropriate formula below and choose an aerator sized for your pond’s volume in gallons: Square/Rectangle: Length × Width × Depth × 7.47 = Pond Volume in Gallons Round: Radius × Radius × Depth × 23.47 = Pond Volume in Gallons How often do you need to replace the air stones?  You only need to replace the airstones if they are damaged. If you are experiencing poor performance or reduced airflow, start by cleaning off any debris or algae that may have accumulated on the surface of the airstones. If cleaning does not improve performance, the unit likely requires 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 wear out, significantly reducing the unit's air output. Installation is easy, and we provide step-by-step videos to help you.  Will a pond aerator keep an open hole in the ice during winter?  Aeration kits infuse oxygen into the water by releasing tiny bubbles from an air stone, which moves the water and allows gas exchange. In most climates, aeration is sufficient to maintain open water in even freezing conditions. If you live in a frigid climate, your water garden may need a little extra help during the winter. In this case, a combination de-icer and aeration kit will ensure that a ventilation hole stays open, 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 maintain a pocket of warmer water for your fish at the bottom of the pond.
