Aeration is designed to infuse oxygen into the pond. With adequate aeration, you improve the overall health of your pond and ensure the survival of your beloved aquatic animals. Other benefits of having a properly aerated pond include eliminating thermocline (it is the border between the colder, deeper water and warmer, surface water), reducing pond muck (common in aged ponds where nutrients accumulate at the bottom of the pond – becoming muck), and many more. At Everything Koi, we carry a great array of evolution aqua aeration products that will circulate your pond water, increase oxygen levels, and remove excess nutrients.
