Nitrite in water comes from the decay of organic matter. It is absorbed into aquatic animals through the gills and reacts with haemoglobin in the blood, preventing oxygen transport, causing blood disorders and possibly killing the animals. A nitrite reading above 0.5 mg/l is considered fairly dangerous.
Measures the alkalinity of water. At a suitable level, alkalinity acts as a buffer that keeps pH from changing quickly; low alkalinity lets pH change rapidly, which can endanger aquatic animals. Suitable for testing water in swimming pools, shrimp farms, aquatic plant cultivation and water used in various industries.
Ammonia matters in aquaculture because it is both a toxin for aquatic animals and a fertiliser for phytoplankton growth. At high concentrations it is dangerous to aquatic animals; in culture ponds most ammonia comes from the animals' excretion and leftover feed.
Dissolved oxygen is an indicator of water quality and is important for aquatic animals and plants; too little oxygen in the water can be harmful to them.
