Should I discontinue my aerator/diffuser over next two winter months and put in my green deicer?

After reading some comments regarding aerators I am now a little freaked out (again). It doesn't take much for me to panic about my fishes clearly, lol.
I am adding some photos or the pond over this week. The really snowy one is from few days ago and the other one is today. I understand that it has not gotten that cold yet for MI but when the temp drops (to 0F as I'm sure it will) then the aerator/air pump which is under the blue inverted rubbermaid looking tub on the other side of the pond will pump super cold water into the pond right? Is it better then to stop the aerator for Jan/Feb and just use a deicer? I have this industrial level deicer from years ago that our pond shop lady said NOT to use because it is too much.
What do you guys think? Is it OK to use or will it keep the whole pond too warm? Is 1250W too much? I could get one that is less wattage like the 300W tetrapond deicer or there are other (100-250W) ones also.
I measured the temp of the water close to the air spout today and it was 34F and went a little deeper away from the air and it was 33F.

1250 watts IS kind of high.

How many gallons is your pond?

I had a 750 watt unit years ago in my 1800 gallon pond. It kept a rather large area of open water here in northeastern Pennsylvania.

The basic idea of a pond deicer is to just keep a small hole in the ice for gas exchange.

I've been using a 250 watt deicer for many years.

I'm going to offer one piece of advice that you didn't ask for - don't freak out. It doesn't change a thing except maybe muddle the brain!

Why would your aerator pump super cold water? It's pumping air. And the aerator itself stays warm, so the cooling will only come from the air passing through the tube on it's way to the pond. Is your tubing exposed? If so, that's one improvement you could make. Bury the line. (I mean next year, if you haven't already.) Once it does snow, that will insulate your air line as well.

Why are you so worried about your pond getting cold? What's your main concern?

I think that may be the size of pond heater Colleen in Canada uses .I am glad all I need is my small pond heater .You also do not want to keep the water to warm because if you have a power outage it could be a problem because fish may go into shock from super cold water after they are used to the heaters keeping the water warmer .Power outages are the curse of all pond keepers .I have a solar back up .I bought the system from harbor freight and 2 batteries and it works pretty good .I originally bought it for my led driveway lights .I need to do a higher mounting system but no time since I have been redoing the inside of my house .

better yet lisak do what I do I use that pipe insulation on my lines for my hoses and my airlines before they go into the water .Cheap stuff to buy but it works and also protects my hoses a little from chewing critters

Good idea! I like to bury all my lines, but you can certainly wrap them before they go underground!

Thanks Lisa. Great advice: Don't freak out!
Also the pump super cold water was a typo. I meant super cold air. Anyway, like you said the air pump will warm up the air and the line (if you look at the pic above) is buried up to the point where it jumps into the pond so some exposure but like you said: does it matter? And yes who knows what my concern is. Just freaked out because its my first time. That being said we just took a long road trip and returned last Saturday (no contact with anyone, just stayed at airbnb house and did not eat out or anything!) and my neighbor watched the pond. We could see it with a camera we had set up so if the air pump stopped or something I could alert her immediately. Nature cooperated and most daytime temps were above freezing. Fish seem ok. They are mostly at bottom but do move around occasionally and sometimes they rise higher in the column for a bit but settle to the bottom soon.

I myself use big red 1500 watt heater, that one heater works good for all 4 connecting ponds that run together all the time. Then I have the ponds covered in plastic domes that I made, and that keeps ice away on all four connecting ponds, about 5000 gallons or so. Here in Canada it's going to -30 Celsius tonight, about (-22 F). That's how I keep my fish safe from ponds freezing

Thank you so much for the info. Sorry for the late response. Guess I'm in hibernation.
Do you keep the pumps etc all running through winter? Can you post some pics of your setup? Thanks. I am assuming the heater does not actually heat the water to warmer (meaning above 40F/5C) temps right? Its just to keep some water surface open?

I just went on your mega-thread and viewed some of the videos that you have posted. Pretty amazing that all of this is thriving in -30C!!!
Super impressive!
Have one question though. As your fish seem to be pretty active, do you feed them? I always thought that once the plants start dying out or going dormant in late fall, and as the temperatures fall further, you can't feed the fish. The reason being that my nitrogen cycle is off, right? So if I kept my pond running and kept it warmer and feed the fish then they will poop etc and otherwise generate ammonia which since there is diminished bacterial activity won't convert to nitrite/nitrate and even if they did then there are no plants sucking up nitrates, right?So isn't that a problem? Just curious.

In Michigan where temps can plummet and stay there for weeks. I would see things as such that a deicer will probably get over powered as they do not agitate the water. and have seen photos where the weather creates an igloo over the heater. I would take advantage of both worlds and use them both the agitation of the air stone along with a pond breather and you should be fine i got 20" of snow on a already frozen pond beside the air stone area and it was covered over by the snow but within 24 hours it had exposed it's self again even though temps had not risen above 20

I've used a de-icer situated over an aerator - air stone about 8 inches below the surface, keeping the water agitated and the de-icer keeping it melted. That works UNTIL you get a massive amount of snow. Then the whole thing is just buried and you're back to square one. I've never used a pond breather, but the make good sense as the "breathing hole" would stay above the many inches of snow that are possible.

I don't feed the fish after September as October can be pretty cold. I let my fish hibernate all winter as the water temps in my ponds over winter are barely above freezing. My pumps and filters are all under water so they are more protected in winter below the ice. I never used to cover my ponds but after adding the new top pond about 4 years ago, the one heater had too work very hard to keep a small opening in ice, so now I cover with cold frames and barely have to use heater. As a matter of fact, my breaker went out couple weeks ago in -36 below zero and ponds only had have covered in ice with large openings in ice where water flows all year. It is important to keep fish in ice cold running water as that kill kill all parasitizes and keep pond very healthy, Its good for cold water fish such as koi to have a cold water winter to keep them healthy, like tout and other cold water fish. As long as water is running good all winter you fish will have fresh oxygen where running water keeps holes open in ice.

Also my pond is really four ponds that all flow together, the top three ponds are always pumped to maximum and then water flows down to bottom marsh area and biggest fish are in the upper ponds as water is fresher and cleaner in upper ponds. It runs sort of like a creek from pond to pond till it gets to bottom pond. I never take my ponds apart to clean unless I am rebuilding one one pond, as I have changed them over the 30 years of wintering my ponds. New liner was added here and there and the new pond pond is 5 feet deep was added 4 years ago, Hope that helps, I have also a U tube channel Colleen Penny and it goes back about 7 years now. Never ever lost a koi and they are never sick with my system. Bacteria continues to thrive in oxygen rich water all winter, as I always have perfectly balanced pond and never add nothing except declor water as added. I do things different than most people. Stay tuned to my threads and follow my ponds and learn how I keep them so clean without ever taking ponds apart.
Here is a look at my spring pond last year... note my Old Bear dog passed away last August at 16 years old

Lovely video. Love Bear Dog! When do you start feeding the koi again? We don't run the pumps in winter because one of them is the kind that will freeze (its in the skimmer box) and the other one is submerged but the filtration unit it goes to (pondmaster or something like that which is above ground) is not allowed to get frozen according to the pond shop guy so we took that stuff and put it in the garage. But we did keep the aerator going and it certainly provides quite some movement at least in one area of the pond and left a nice hole most of winter. When it got really cold, I turned on my heavy duty green heater and it worked well. Hopefully the worst is behind us now!
