Question, problem with my pond.
I am having a major ammonia problem with one of my ponds. It is not your typical pond, it is a 650 gallon blue poly tank, like the ones koi are in for shows. It is bare bottom, with a 900 gallon pump, and 1600 gallon filter with UV light. 4 fish in it. The pond co says I should be able to put more in it than that. We have done a 75% water change twice in the past week and a half, as recommended by a friend who owns a pond company. Ph is 7.0, Nitrates and Nitrites are all at the lowest on the test chart. I am using API test kits, drops not strips. Ammonia is around 2.0. The pond co did tests on the water, got the same readings as mine, including the ammonia, so my tests are not bad. There is no run off, the tank is half in the ground, half out. No trees, no dogs to pee in it.
They are as baffled as am I. We have 2 other ponds, and the results are all great. Same water, etc. Tested our tap water and the ammonia level is at 0. I contacted the company for the poly tank and they say nothing could be leeching from the tank, which is our only last assumption.
Any suggestions? Thanks for your time.
