Tetra Test pH Freshwater

Tetra Test ph. The Tetra Test ph measures the pH value of aquarium and pond water accurately and reliably. The pH value in water is an important criterion for the balance between acids and bases. Fish, microorganisms and plants react very sensitively to sudden changes in this balance. The ideal pH value should therefore be between 6.5 and 8.5, depending on the species of fish being kept. The test offers good long-term stability and a high range. It is suitable for freshwater and saltwater aquariums and ponds. Contents: 10 ml. Caution: Liquid and vapor highly flammable!
