I have air pump and venrura working in pond.Ammonia was a little high as was nitrate, nitrite and ph normal. I have over last 3 days change about 1/3 of water. All other fish about 20 are ok, tried feeding pea but always seems to eject it after a while.

The nitrate is not to much trouble but the amonia you need to get that down to 0 ASAP and stop feeding till the amonia is at 0 again have you had a scrape done to check for any parasites? if not it might be a good idea and as its 25 years it might just be down to old age and is just passing on as you say all your other fish are ok.

as worthy says,no feeding,water change until 0 amm,you can give the koi a salt bath.10 min,it might help.u ent said wot kit u are useing?
