The CrystalClear KoiAir 2 Pond Aeration Kit provides powerful aeration to water gardens and features. Designed as a complete aeration solution, the CrystalClear pond aeration system contains everything you need to introduce aeration to large water gardens and features with a quick and simple installation. Running on 35 watts, the whisper-quiet SilentAir aeration pumps are the heart and soul of our KoiAir aeration units. Costing virtually nothing to run, you can feel good about providing constant aeration to your pond. Our heavy-duty flexible airline is designed to sink to the pond's bottom even when filled with air. EasySet airline is extremely resistant to cuts, snags and kinks for maximum performance with minimal headaches. Each KoiAir diffuser plate utilizes a sturdy base plate and incorporates a 3/8 in. barbed inlet for quick hook-up to the included EasySet airline while providing threaded female outlets to accommodate membrane diffuser sticks. Designed to improve oxygen absorption, our diffuser membrane delivers all of the performance of air stone diffusers without the hassles of replacing cracked stones or frequent cleanings due to debris accumulations. Virtually maintenance-free, the membrane diffuser stick resists clogging and its flexibility eliminates the possibilities of cracking and leaking.
