we still have some ice on pond water temp right around 38 bottom 41 top we have a koi toilet with aerator was holding off but found a couple sinkers today
so i set everything up after work all ready to go wasn't sure if aerating from bottom will cause to much cool down first winter with koi in this pond 13000 gal

In my opinion no because your surface and bottom temp are very close. They can handle a 3 degree shift for sure.

With my bog running my pond has gone from 56 or so a week plus ago to 44 and my goldfish have done fine. The temperature did drop slowly. I thought our temps were heading up, but this am it is 22f, the bog has a lot of moving water surface which causes a cool off of the pond water when our temperatures drop.
