JAPANESE KOI FISH / KOI POND / KOI PONDS / KOI FISH ..
It sounds like you are still running the filtration system in your pond which should provide some aeration. However, I would still run additional aeration but reduce the flow like you thought. If your weather stays below freezing the water temperatures will stay low. I do not know the kinds of fish but if they are Koi or hardy goldfish you will be alright. Please refer to my latest article “You Can’t Make Mistakes”. I would always provide aeration in all four seasons.

I hope you get to enjoy your pond to its fullest! I don’t recommend koi for a pond that size, but highly recommend introducing goldfish that are wonderful pets, colorful, easy to care for, and kids LOVE them. Goldfish would be best for that type of pond. Good luck and cheers! Mike
Combining Style and Function with Koi Fish Ponds.
This site is a resource for Koi fish enthusiasts and pond keepers. Many pictureshelp identify Koi varieties. Our focus is on how to keep Koi fish happy and healthy. Wesupply imported Japanese Koi fish as well as Butterfly Koi fish from the finest breeders.An ideal way to have the beauty of a water garden AND the distinct pleasure of a koi pond is to have both! - a lovely water garden tippling off into a koi pond. The plants can’t be disturbed (or eaten) by the fish because the fish can’t get to them and the fish can be viewed in all their glory, unfettered by pots and plants.A koi pond is a purpose built habitat for those lovely fish we call “Living Jewels” and as such, differs from any other garden water feature. To introduce koi into other types of water features is usually a disaster waiting to happen and though one can get away with it for awhile, the end result is predictable. So, instead of doing what so many do, that is dig a hole, throw in a liner, add water and a few fish, and call it a koi pond, we want to help to get it right the first time. You only need to do it right once but you can get it wrong over and over.An ideal pond for the average hobbyist is between 23 and 25 feet long by 12 to 13 feet wide and 3 to 4 feet deep. (The 1% or less of koi hobbyists who want to grow jumbo koi or keep fish primarily to compete in shows with, will want much deeper ponds of 6 to 8 feet). This size pond can accommodate 15 to 20 mature fish (24 to 28 inches) giving them plenty of room to exercise and, will not look overstocked and crowded. Here’s how we calculate the volume of water in this pond: Length X width X depth = cubic feet X 7.5 gallons per cubic foot = volume in gallons. So, 25 X13 X 3 X 7.5 = 7312 gallons. However, this is only an approximate figure as the pond will not normally be a perfect rectangle and the shape may be more freeform. We will only know the exact volume of pond and filtration system upon filling the feature and metering the input. And it’s extremely important to know the exact volume.
