Ammonia (NH3) is a natural, toxic by-product of animal metabolism and the decomposition of animal and plant waste materials. Without regular testing, the ammonia level in your aquarium could rise to a level that is fatal to your fish.

The Tetratest® Total Ammonia kit was professionally developed to accurately determine the ammonia level in your aquarium water. The kit contains enough material for 25 tests, including one 6-ml test reagent #1, one 10-ml test reagent #2, one 17-ml test reagent #3, a test vial, color scale, instructions and recommendations.

Tetratest® Total Ammonia kit is safe and accurate to use with other chemical products that remove, reduce or detoxify ammonia from the aquarium and which can cause interference with less-expensive single reagent test methods. This kit is suitable for Freshwater (including outdoor ponds), Brackish and Saltwater systems.

TetraPond Kits are both reliable and accurate, using professionally designed methods to determine if your water is safe for Koi Fish.

Nitrate is produced from the breakdown of nitrite in the filter. Nitrate is relatively harmless to freshwater fish, but its presence can indicate a deterioration in the aquarium environment, and high nitrate will encourage algal growth.

The only way to know what the nitrate level is, is by testing it with a TetraTest Nitrate kit. Regular testing will help you to assess the overall health of the environment.

Nitrite is produced from the breakdown of ammonia in the filter. Nitrite is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter. However, in new ponds, or if the filter bacteria are damaged, the nitrite level may become toxic.

The only way to know what the nitrite level is, is by testing the water with a TetraPond Nitrite kit. Regular testing, especially in new ponds, will prevent damage caused by nitrite poisoning.

Oxygen is vital to the well-being and overall condition of fish, plants and filter bacteria. Water contains far less oxygen than air, and at times it can become limiting. It is important to check oxygen levels from time to time, particularly at warmer times of the year. The only way to check the oxygen level is with a TetraTest Oxygen test kit.

pH is a measure of how acidic pond water is. Fish do not like fluctuating pH levels, and need to be kept within a specific pH range. The only way to determine the pH of the water is with a TetraPond pH kit.
