Last year I removed both the pumps from my pond and cleaned them really good with fresh water. After I cleaned them I soaked them with food grade silicone spray so it would be safe for the fish when I put them back in the pond come spring time. I doused every part of the pump I could. The rubber bushings and sprayed directly inside the impellers. Then I stored them in my warm attached to the house garage where even if there was residual water inside the pump somewhere it wouldn't freeze. This year Im wondering if I should just leave them in the bottom of the pond (about 3-3.5ft deep). It isn't out of laziness because when it comes to my pond maintenance Im sure not lazy. I just wanted to get some takes on what everybody else thinks....by the way the pumps Im referring to are the pump that controlls my waterfall (biofalls) and the pump that goes to my filter. I will be using 2 other pumps that control the airstones throughout the winter. Im still up in the air on using external pumps for that or using the Little Giant submersible pumps. Thats another discussion actually already in another thread

I have done that before but started bringing them in and storing them in a barrel of water in my basement. Reason being, it makes spring clean up easier with a clear pond bottom

If you're not going to have them running, I would remove them from the pond.
Otherwise, the pumps will serve as any other crevice in your pond and various critters will take up residence inside them.
That could make it difficult to start them up in the spring and possible cause some damage.

If I DON'T run the pump I'd have a solid block of ice. Last winter was one of the worst for the pond we stayed single digits for 10 days and the warm up was slow. I think at one point it was 70% frozen. I was concerned about my fish and hardware but we made it thru.

I leave mine in the pond but it only gets cold here for 2 maybe 3 months .I just lower them to the bottom .I put in a thousand gph pump and put the pond heater over top of it ..I think last year I turned me heater on 3 times and my waterfall filters ran until Jan. .I used to keep my fountain pond running in NJ almost all year round .The top part was not running but the lower one was and it was just over 2 feet deep .My son put in a stock tank heater and it kept a lot of it open .

If my pump was like that Id run it all year round as well...my waterfall is about 5-6ft above the pond. Not possible to let that run all winter. The other pump I have goes to an external filter. The filter would freeze during. Also not feasable

I have to disconnect my waterfall in winter and I just leave the main pump circulating underwater to keep the ice broken up.... Didn't work to well for me last year but we made it. Removing the pumps is a good idea if they're expensive ones, I've had to replace more than one pump after a long hard winter. But I think you'd be fine to leave a submersed one in, even running. You have WAY more gallons than I.

Those guy's don't seem to mind a little ice. I always get some but last year was the worst. I was actually surprised to see my fish in spring.
