I live in Maryland and I have a pond that is 900 gallons, has a water fall, and has a rubber liner. I put a small heater in the pond last winter to make sure there was an oxygen exchange. I have cattails, lizard tail, yellow flag, pickerel weed, about two types of water lilies, a lotus, and arrow arum in the pond. All are in pots. Fish include about 7-8 fish: koi, two fantails, and about 4 Eastern Darters. The pond is under a couple of large trees: an oak, tulip poplar, and white pine. Can anyone list the steps I should take to winterize the pond?
On another note, I recently realized that the water in my pump/skimmer area drops to about 50% of recommended volume and I hear the pump sucking in air. I am wondering if I may have a leak. Is it recommended to remove the water plants over the winter? I question whether after 4 years of leaving my potted plants in the pond may have allowed the roots to penetrate the liner as the roots have burst through some of the plastic pots. Any insight is appreciated.
