NO3 test

This nitrate test is for aquarium keepers who fertilise their tanks and want to know the actual nitrate level before adding more. Nitrate readings show whether the water needs a fertiliser dose or whether the current amount is already sufficient.

Why it matters

• Elevated nitrate concentrations can be harmful to fish, so the level needs to be checked when fertilisers are used.
• Both a shortage and an excess of nitrates are unfavourable for plants, which makes an exact reading useful for plant-focused setups.
• The result is used directly to choose the appropriate fertiliser dose, instead of dosing by estimation.
• The kit is suited to regular checks of a tank that receives fertilisers of various types.

What it works with

The kit is designed for freshwater aquaria in which nitrates are supplied by fertilisers, particularly planted tanks. It fits any setup where the dosing of nitrogen-based fertilisers is part of routine care. The colour scale is used to compare the test result with the expected nitrate level.
