Achieve excellent aeration results while maintaining a low profile. This chemical-free process is created by combining a floating electric motor operating at 1725 RPM with a high-efficiency stainless steel propeller system. The random boil effect results in an oxygen transfer rate starting at 3 lbs. per hour. This continuing cycle of oxygen circulation and induced wave action prevents thermal stratification and supports aerobic bacterial action, resulting in clearer, cleaner, odor-free water.
