Hi everyone,
First time on this site, looks like a lot of great info and resources available.
Anyway I'm at a loss, I have a large pond probably 6000 gallons with all koi from 1 inch fry to 12inch. Qty of fish is about 14 fish not including fry from 1-3 inches, they hide well.
Pond has a sand filter, waterfall, skimmer and large bubbler that all are still running as of 1/12/17.
Big koi are fine but smaller fish are dying off, I'm in NJ so our winter has not been bad and the pond hasn't frozen over.
Any ideas would be greatly appreciated.
