Aquarium use

The checker is useful for initial measurements of nitrite when trying to establish good ammonia/nitrite/nitrate control. Suitable for all types of aquaculture, the ultimate aim is to decrease nitrite levels so that the low range of ultra-range nitrite checker can be used for optimum tank health.

Nitrite can lead to tissue damage, illness and death of aquatic life, so regular checks can help aquarists identify rising nitrite levels before fish begin to suffer.
