Fast and easy way to assess the general hardness in freshwater aquariums and ponds. This tool offers straightforward and dependable monitoring of water parameters. It identifies the optimal general hardness levels for your freshwater aquariums and ponds.

Quick assessment to evaluate the nitrite levels in both freshwater and marine aquariums and ponds Nitrite is a harmful nitrogen compound that arises when the bacterial ecosystem is disrupted or during the establishment of a new aquarium. This test provides precise measurements of the nitrite levels in your water. Utilizes a laboratory-grade comparator system to adjust for the natural color of the water: simply fill glass vials with your sample, add reagents to one vial, position the vials in the holder, and compare the results against the color chart. Application: when initializing a new freshwater aquarium, conduct tests daily for three weeks. For marine water setups, test once a week. Also recommended when dealing with fish illnesses or fatalities. For thorough instructions and troubleshooting advice regarding water testing, visit the JBL website under Essentials/Aquarium or Pond. Included in the package: 1 nitrite test kit providing approximately 50 measurements, complete with 2 reagents, 2 glass vials with screw tops, a syringe, a comparator block, and a color scale. Reagent refills are available for purchase separately.
