Help and advice on shopping for: Freshwater Nitrate Test Kits
Determine the nitrate content in your aquarium
High nitrate (NO3) levels in your fish tank can lead to increased growth of unsightly algae which also poses a health problem to your fish. At Swell UK we provide an excellent range of nitrate test kits from leading brands that allow you to accurately measure nitrate levels in your tank and can be used in both fresh and saltwater aquariums.
What are nitrate test kits?
The ultimate outcome of mineralisation in the aquarium is nitrate. It is non-toxic to fish even at quite high concentrations, although it damages plant growth and the well-being of some fish species. If phosphate is present in the water along with nitrate, too high nitrate levels might stimulate undesired algal development. To solve the problem, use a nitrate remover and keep your tank healthy and algae free.
Why might I buy nitrate test kits?
Nitrate isn't as harmful to fish as it is to humans, but it does stress them out, making them more prone to sickness and limiting their longevity. It's a good idea to keep track of nitrate levels in your aquarium on a regular basis, and understanding your tank's nitrate levels is essential for maintaining optimal water chemistry for your aquatic life. Our nitrate test kits provide precise results, allowing you to take control of your nitrate levels.
What are the main types of nitrate test kits?
Nitrate is the end product of biological filtration and the result of the decomposition of nitrite. It can also be present in tap water supplies. It's a key cause of algae growth and in high concentrations can cause fish and plant health problems as they are starved of nutrients. The Tetra Nitrate Test Kit should be used every 1-2 weeks to monitor levels properly. Just like many of the kits we carry, this kit uses a colour change system to give accurate results, simply compare your findings to the colour chart included.
What accessories should I buy with nitrate test kits?
Live aquatic plants are nature's nitrate filters, and readily soak up nitrates, and use them as fertiliser. Heavily plant any nitrate-laden aquarium with fast-growing live plants, and they will remove all the nitrate within days or weeks.
