What is Swell Aquarium Nitrate Remover? Swell Aquarium Nitrate Remover is a 100% natural product that is highly concentrated and effective at reducing nitrate (NO3) in freshwater aquariums. Nitrite (NO2) and nitrate (NO3) are harmful substances that are produced as a result of biological processes, such as the breakdown of waste from fish, plants, invertebrates, and uneaten food. How does this treatment work? Initially, ammonia is produced by biological processes, but it is then converted into nitrite by bacteria from the Nitrosomonas group (which can be found in the bacterial activator Swell Aquarium Biological Starter). Nitrite is then converted into nitrate by bacteria from the Nitrospira and Nitrobacter groups (which are also present in Swell Aquarium Biological Starter), and nitrate accumulates in the aquarium. To reduce the levels of nitrate, you can do partial water changes and clean the gravel, and you can also use Swell Aquarium Nitrate Remover periodically. The presence of nitrate is a good sign that the aquarium is functioning properly because it means that the nitrogen cycle is complete and the filter is "mature". However, high levels of nitrate can also cause an increase in algae growth. The maximum level of nitrate in an aquarium is 20-30 mg/lt, and to keep it at this level, you can do the following: Do partial water changes of 10-15% at least twice a month, using Swell Aquarium Dechlorinator and Swell Aquarium Biological Starter with new water. Clean the filter once a week. Clean the gravel once a month. Provide the fish with the correct amount of food every day. Use Swell Aquarium Nitrate Remover regularly when the nitrate levels start to rise.
