heartlander, Winter aeration will depend on several things, some listed below. Can you tolerate thin unsafe ice, what is your demand for DO in the winter months,high OM ponds may be candidates for winter aeration. Any problems in the past? Do you have stricly warm water fish, probably yes then try to keep the deeper areas above 39F and some aeration can send small ponds colder than that quickly.If no ice then in older ponds I still prefer to circulate in a shallow area "IF" Im not sure of the DO level. If your going to add beneficial bacteria when the water warms up see note to loretta.
Pond has been close to 3 yrs. Has bluegill and some LMB -I HOPE it still has LMB... so yes I would be concerned about super-cooling in winter if we're having a colder than normal spell. This current one has been such a winter. We are just far enough south to be clear of lake effect weather, so find the winters normally to be pretty mild in comparison (to where we lived before). Little ice, 30-deg. temp swings within 24 hrs., etc.
Thanks for the info on the bacteria. Maybe bacs won't be needed at all once things get circulating. Can't hurt, at any rate.
