I am located in Northwest (Seattle area).
I am appreciating everyone's input here!
The koi I am looking for growth is 3 years old, the one I am looking for beni is 2 years.
I have a heather, so I could in concept control at 52-53 (but should I not feed so cold?)...last winter I kept at around 60 C
If I do decide to "season", for how many months should I keep at cold temperature?
