Hi everyone. I purchased a home with a koi pond which we have completely cleaned out and added fresh water with a dechlorinator and added barley straw. We know nothing about koi ponds in what to do now as far as purchasing koi fish and when we can add new fish and what we need to do from here on out. The previous owners didn't leave no information or details what to do. Our guess is it's about 3 ft deep. About 500-750 gallons. It's got a liner, pump, deicer, waterfall
