The pH value or “acidity level” indicates how acidic or basic (alkaline) a water is. Pure water reacts neutrally and has a pH value of 7. If the acidic components predominate, the pH value drops (pH < 7); if the alkaline components predominate, the pH value increases (pH > 7). Many organisms react extremely sensitively to strong fluctuations in pH.

In freshwater aquariums, the optimal pH range for most fish and plants is between 6,5 and 7,2. However, special biotopes such as Lake Malawi in Africa also have higher pH values ​​of up to 9,0. In saltwater aquariums, the optimal pH value is between 8,0 and 8,5, as in the oceans. Strong fluctuations and excessive drops or rises in the pH value should be avoided at all costs and the acidity level in the pool should therefore be checked regularly.

– Shake the dropper bottle before use!
– Rinse the glass cuvette with tap water and then several times with aquarium water.
– Using the dosing syringe, fill exactly 5 ml of aquarium water into the glass cuvette.
– Add 1 drop of pH test reagent, close the glass cuvette with the stopper and shake the solution briefly.
– Place the glass cuvette on the white inner circles of the color fields and compare it with the surrounding color fields. To do this, look into the open cuvette from above.
– Read the measured pH value under the corresponding color field.
– After the measurement process, rinse the glass cuvette and syringe thoroughly with tap water.
