We have a 1200 gallon pond with 4 koi that are 5 and 6 years old; living in Hillsboro, Oregon. Since we changed the filter to an Ultima II in July (what a waste of money), the pond has not ever been in balance, with ammonias running high and PH creeping low. Even in the winter with water temperatures low and no feeding, the ammonia within a few days of water changes or Amquel, starts to climb. We tried seeding the filter with Microbe Lift and later, when that apparently did not work, some kind of dry bacteria. Nothing seems to work. They are getting very stressed and it is affecting their skin. I do not know what to do. Any ideas would be appreciated! Thanks
