Zoolek Aquafix NO3 Nitrate Remover

Zoolek Aquafix NO3 is a nitrate remover in flow bags that binds the nitrate ions accumulating in aquarium water. According to the product data, it limits the nitrate content without the need for a water change.

It is intended for aquariums with fish, where nitrate builds up as the final product of the nitrogen cycle. According to the product data, too high a nitrate level can lead to rapid algae growth.

The bags contain a selective anion exchanger in chloride form. During ion exchange, the nitrate ions in the water are replaced with chloride ions from the exchanger. The bags can be regenerated in a table salt solution and reused many times.

Place the bag where the water flow is strong, for example near or in the filter. According to the product data, how quickly the exchange capacity is used depends on the water flow rate. Check the nitrate content with the Aquatest NO3 test.
