 HI 96700 AMMONIA PHOTOMETERS
Ammonia is often an excellent indication of the presence of animal or plant microbiological decay. It is tested in fish farms (fresh and salt water tanks) due to the damaging effects of its toxic nature. Its presence in rivers and reservoirs normally points to agricultural and/or civil pollutants. Ammonia is tested in ponds, lakes, rivers, portable water, boiler feed water, sewage, industrial and waste water.
HANNA offers instruments for low, medium and high ammonia concentrations.

Why we need to test Koi ponds.
Effects of Ammonia:
Ammonia tends to block oxygen transfer from the gills to the blood and can cause both immediate and long term gill damage. The mucous producing membranes can be destroyed, reducing both the external slime coat and damaging the internal intestinal surfaces. Fish suffering from ammonia poisoning usually appear sluggish, often at the surface as if gasping for air.
Source:
Ammonia is a gas primarily released from the fish gills as a metabolic waste from protein breakdown, with some lesser secondary sources such as bacterial action on solid wastes and urea.
Control:
Ammonia is removed by bacterial action in the bio-converter and a small amount is directly assimilated by the algae and other plants in the pond. The bacteria consume the ammonia and produce nitrite as a waste product. A significant portion of this bacterial action can occur on the walls of the pond as well as in the pipes and bio-converter. Ammonia readings may increase with a sudden increase in bio-converter load until the bacterial colony grows to accept the added material. This can happen following the addition of a large number of new fish to a pond or during the spring as the water temperature increases. Fish activity can often increase faster following a temperature increase than the bacterial action does. A bio-converter that becomes partially obstructed with waste and/or develops channels through the media may operate at reduced effectiveness that can also cause the ammonia levels to increase.
So you need to TEST, TEST, TEST, TEST.... We use this Ammonia photo test meter at Michigan Koi. |
