Giesemann Nitrite NO2 Professional Test Kit (OVERSTOCK)

Giesemann Professional Nitrite NO2 Test Kit

The GIESEMANN nitrite test is a specifically precise test focussing on the lower range ranging to 2.0 mg/l for the regular analysis of the water values.

Nitrite (NO2) is a chemical nitrogen compound and is toxic to fish and invertebrates. As Nitrate levels increase over 0.1mg/L  , the function of haemoglobin necessary for the transport of oxygen in fishes' blood become blocked. Lethal concentrations cause chronic stress lowering fish's resistance to parasite and bacteria attacks, reducing food intake and growth, and can result in death.

In newly established salt water aquariums significant nitrite overconcentration can occur, especially if bacteria cultures aren’t sufficiently present.

Typically, established aquariums with a functioning nitrification do not show critical nitrite concentrations. If the concentration should rise nevertheless, ammonia (NH3) absolutely needs to be measured too. Increased Nitrate levels could be due to fish overpopulation, overfeeding and/or the use of medication that can disrupt or kill otherwise healthy bacteria.
