 Water Quality in Koi Ponds


It has been said, "take care of the water quality and the fish will take care of themselves."

Truer words were never spoken. There are only two reasons why fish get sick.
1. Parasites  2. Bad water quality

Keep in mind that just because the water looks crystal clear, it may still contain deadly amounts of ammonia and or nitrite. In order to avoid problems the ammonia and nitrite must always be 0, zero, none, nadda, no other reading is acceptable. There are other factors in water quality also. pH, Water hardness, softness (GH), carbonate hardness (KH)

The following links will explain in more detail.
