I shut my aerator off for the winter, will I have to introduce it slowly again in the spring?
George – Albany, NY
As pond owners we buy aeration systems for our water bodies with the intentions of creating a cleaner and healthier environment for both ourselves and our fish. While aeration systems are great at eliminating water stratification and promoting the ideal environment for a healthy pond, the key to proper use is proper installation.
The surface of your pond reacts to the ambient air temperature and warmth from the sun considerably faster than deeper regions. As we head into spring the temperature will begin to rise as the sun shines down on your pond. The top layer of water in your pond will begin to warm up quickly while the bottom of your pond stays dark and cold. Furthermore, the surface of your pond is exposed to oxygen which is naturally wicked into the water column but remains only in the upper layers. This formation of warmer and cooler layers of water is known as stratification. Stratification can become a potential hazard as the two different layers of water will sometimes flip or “turnover” and mix together causing a sudden change in water temperature and dissolved oxygen levels which, depending on its severity, can make it difficult for your fish to adapt to the quickly changing environment.
Airmax® Aeration Systems are designed to infuse oxygen into your water column from the bottom of the pond while continuously circulating the water. This constant action aids to prevent water stratification for occurring. However, when aeration is introduced suddenly and continuous to your pond you are, in essence, creating a man-made turnover by forcing all of the water at the bottom of your pond to the surface.
When installing an aeration system in your pond, or upon reintroduction of your system after winter removal, you will want to run your system in small increments that grow in duration over the course of a week. Think of this process as the same way you acclimate new fish to your pond. You wouldn’t just grab a new fish by the tail and toss them in your pond, you float their holding container in your pond and slowly mix some of the water together to give them time to adjust to the variations in each environment. By running your aeration system for only an hour the first day you install it and doubling the run time each day after, your aeration system will be running continuously by the end of the week while keeping your fish safe from pond turnovers.
