I keep a tropical aquarium that is heavily planted. I constantly check the water conditions. ammonia, nitrites, nitrates, and ph. each can cause stress on aquarium fish. some handle certain conditions better than others. Would there be any test that i could do on the pond water that might point me in the right direction? The only thing I can think of is my pond may be too fish heavy. does overcrowding cause oxygen issues only, or do other things such as ammonia and nitrates come in to play? Also, would oxygen be an issue this time of year?
