Lower ammonia in koi pond
We have been putting live bacteria in for two weeks and we just switched to ammo-chips five days ago and the ammonia is not going down. It is still in the dangerous zone. We need to get it down fast and a water change is not possible at this time. HELP!! please!
We do have a lot of fish but we have a very large filter in.
We cut down the feeding by 1/2 two weeks ago.
