Once again, my koi survived a brutal Ohio winter. This winter had some serious freezing but my pumps in my largest pond kept pumping away. There was ice on the pond but a clear area from the pumps plus the fish stayed in the deepest end.
I closed up my deck pond and my small backyard pond and brought those fish inside. All 7 Koi are thriving. I put 2 large goldfish in another downstairs pump, and they are doing good.
As I started doing last year, I added bio balls to my pump for the koi and, as you can see, the pond stayed nice and clear. All I've had to do is add water as the water gets sucked into the dry winter air.
I'll probably put the open the small backyard pond in a week or 2 and add the goldfish. The deck pond probably won't be opened until mid-April. I won't transfer the koi until then. They all grew but won't go into the large pond at this time. I need to be certain they are large enough that the bass doesn't get them.
