Description
The Tetra Test ph accurately and reliably measures the pH value of the aquarium and pond water. The ph-value in water is one of the most important criteria in the equilibrium between acids and bases. If this balance suddenly changes, fish, micro-organisms and plants react extremely sensitively to it. The ideal pH value should therefore be in the range of 6.5 and 8.5, depending on the species of fish being kept. Good long-term stability and high range. Suitable for fresh and salt water aquaria and ponds.
