NT Labs - Ammonia Water Test Kit
NT Labs - Ammonia Water Test Kit What is ammonia? Ammonia is the main waste product produced by fish as a result of feeding. It can also be generated by the decay of uneaten food or decaying organic matter, such as plant leaves. It is invisible to the naked eye and its presence or absence cannot be determined by looking at the water alone. It is extremely toxic to the fish but is broken...

NT Labs - Nitrite Water Test Kit
NT Labs - Nitrite Water Test Kit What is nitrite? Nitrite is produced by beneficial filtration bacteria as they break down the harmful waste ammonia excreted by the fish. Like ammonia, it is not visible to the naked eye. Although it is not as toxic as ammonia, nitrite is still very damaging to the health of the fish. Nitrite itself is broken down into nitrate, which is practically harmless...

NT Labs - Nitrate Water Test Kit
NT Labs - Nitrate Water Test Kit What is nitrate? Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (ammonia and nitrite). Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth. What is the correct nitrate level? The level of nitrate is dependent...

NT Labs - Broad pH Water Test Kit
NT Labs - Broad pH Water Test Kit What is pH? The new Broad Range pH Test is for testing water within the pH range of 6 – 9. This pH test now covers the pH range more likely observed in your pond and also offers improved precision with 0.5 unit determination. What is the correct pH level? There is no definitive correct pH as different fish species have their preferred pH...

NT Labs - Hardness GH & KH Water Test Kit
NT Labs - Hardness GH & KH Water Test Kit What is KH? KH, also known as “total alkalinity” or “carbonate hardness”, is a measure of the buffering capacity of the water in your pond. The buffering capacity refers to how well it can resist changes in pH. What is GH? General Hardness is a measure of the total amount of minerals dissolved in the water....

Tetra Test Ammonia Test Kit
Tetra Ammonia Test Kit Simple to use kit for determining ammonia levels. Ammonia (NH3/4+) is excreted by fish directly into the water, and is also released from the breakdown of solid waste and uneaten food. Ammonia 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,...

Tetra Test Nitrite Test Kit
Tetra Nitrite Test Kit Nitrite (NO2-) 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 determine the nitrite level is by testing it with a TetraPond Nitrite...

Tetra Test Nitrate Water Test Kit
Tetra Test Nitrate Water Test Kit Nitrate is the end product of biological filtration and the result of decomposition of nitrite. It can also be present in tap water supplies. It is a key cause of algae growth and in high concentrations can cause fish and plant health problems as they are starved of nutrients. Use the Nitrate Test Kit every 1-2 weeks to monitor levels properly. In a...

Tetra Test Oxygen Test Kit
Tetra Oxygen Test Kit All living organisms, even plants, require oxygen to survive and thrive. A low oxygen concentration will cause the pond inhabitants to slowly suffocate making them increasingly likely to become ill. Oxygen is also required by a ponds biological filtration to convert toxic ammonia and nitrite into nitrate. The Tetra Test enables you to easily measure oxygen levels...
