    A RWK Series Air Pump will add oxygen to pond water, help reduce algae, discourage water breeding insects such as mosquitoes, and eliminate odor problems associated with stagnant water. RWK Air Pumps also help ensure a healthy home for desired aquaculture by preventing stratification.

    Microorganisms, plants, fish and other animals in your pond need oxygen to live. A waterfall may not be providing enough oxygen to keep your ecosystem healthy and in balance. A pond aerator increases dissolved oxygen levels throughout the pond.

    These air pumps provide increased water aeration to your pond.

    Oxygenated water is critical for keeping fish and aquatic life alive and healthy. Aerating the water also benefits the bacteria living inside biological filters.

    Pond Air Pump During Winter

    In freezing temperatures – the rising air bubbles from an RWK air pump will keep a hole open in the ice. The churning bubbles prevent the pond from completely freezing over. Keeping a hole open in the pond is critical for the health of your fish.

    An open hole in the ice allows for potentially harmful gasses to escape the water. Keep your RWK air pump running in your pond at all times. An RWK air pump uses less electricity than a pond heater at preventing total ice over.

    During extended periods of below freezing temperatures, an outdoor air pump can hyper-chill the water. This can become harmful to some pond fish. The best way to prevent hyper-chilling the water is to move the RWK air pump indoors or inside a shelter with just the airline and diffuser outdoors. This will allow warmer air to be pumped into the pond and eliminate the risk of hyper-chilling the water.
