Let the wind make your pond healthy again by installing the Outdoor Water Solutions 24' Deluxe Windmill Aeration System on your property. This 24' windmill feeds a compressor connected to airlines that lead to air stones at the bottom of your pond. The compressor pumps air to the air stones, which send oxygenated bubbles up from the bottom of your pond. This adds circulation to standing water, which increases its health by fighting scum, algae, and muck. Keep track of your air stones with the 2 included duck decoy markers that float above them. This windmill can be installed in as little as 12 days and has a single-diaphragm system that keeps maintenance simple. The aerating windmill has a 3.04.5 CDM wind rating. Includes 1 roll of non-weighted 100' airline, 2 rolls of 100' weighted airline to sink your airline to the bottom of the pond, 2 air stones, 2 foot valves, set of pivot points, 2-way selector valve for airflow regulation, 2 hose connector packs, 2 air stone housing buckets, and 2 duck decoy markers. Mfrs. 5-year warranty on compressor components.
