This is the second summer for my pond. It is 22 ft by 11ft and 3 ft deep. We currently have about 40 fish- koi n goldfish. I've noticed on fish with fungus around his mouth and two fishes with issues on their sides n back. Looks like their scales r coming off. I've already lost one fish with a large nasty sore on the side of his body. I suspect it's fungus n bacteria. My local pond store gave me medicated fish food. What else should I do? Throughout the winter n even now the ph is at 8.4 and the ammonia is near zero. I have a biofalls n two air stones going. I have been adding biologist n have submerged oxygenators as well as surface oxygenators n marginal plants. I've had to do several water changes this spring to get the salt level down to .2 ppm. This past winter we had ich n we had to elevate the salt level. Any help would be greatly appreciated.

What is your flow rate? (Pump size)?
Is this an eco-system pond or dedicated formal Koi pond?

Can't remember exactly the flow rate but I know it was large. We purschased a mega pond kit that would take care of 2000 gal water. It is an eco-system pond.
Yes! That is what the dead fish looked like. What do I do. The pond store guy gave me medicated food and said it would take care of both bacteria and fungus. From what I am reading medicated food does not take care of bacterial infections.

Medicated food treats internal bacterial infections.

Sorry, but your figures don't jive.
An eco-system pond of the dimensions that you gave would have a 4000+ gallon capacity. A 2000 gallon kit would not have sufficient liner for this size pond. Not to mention that the skimmer, filter and pump included in a 2000 gallon kit would be dangerously undersized for use in a 4000+ gallon pond.
Sorry. You are right. I was probably thinking about the price of the pond kit. I checked and the pump is 8000 GPH with a BF 3800 filtering spillway and a PS 7000 skimmer.
