Should I turn off Aerator in winter as I have an underwater spring that creates a winter warm spot and TFS have survived 4 winters? Will aerator bring colder surface water and mix with warmer spring water and kill off TFS? Is there any advantage to run aeration system through the winter? 9 ac pond in Chester ,S.C. rarely freezes solid but never in the area of the spring.

Thank you always for your excellent informative advice.
