NTLABS pond water mini test strips.

Description

When to use?
The key to successful fish keeping is excellent water quality. The Pond Water Mini tests three water parameters: pH, Nitrite and Ammonia.

Ammonia:
What is ammonia?
Ammonia is excreted by fish as a waste product. It is extremely toxic to fish, and is broken down into less toxic nitrite by the beneficial bacteria in the filter of your pond.

Nitrite:
What is nitrite?
Nitrite is produced by the beneficial bacteria in the pond and filters as they break down harmful ammonia excreted by fish. Although not as toxic as ammonia, nitrite is still very damaging to the health of the fish. Nitrite itself is broken down into nitrate which is significantly less harmful to fish.

pH:
What is pH?
pH is the measure of the acidity or alkalinity of the water in your pond.  The pH scale runs from 0 to 14. Very acid water is pH 0 and very alkaline water is pH 14. Neutral water that is neither acid nor alkaline is pH 7.

How do I do the tests?
A full instruction leaflet is included in the pack which talks you through each parameter, what it should be, and what you should do if the readings are incorrect.

This test kit reports concentration in terms of nitrogen (NH3-N) or (NO2-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 1.21 (NH3-N) or 3.29 (NO2-N).
