For determining the pH-value in freshwater aquaria
The pH value or “degree of acidity” indicates how acidic or basic (alkaline) water is. Pure water is neutral and has a pH value of 7. If the acidic components outweigh the alkaline components, the pH value falls (pH < 7), if the alkaline components outweigh the acidic components, the pH value rises (pH >7). Many organisms are extremely sensitive to significant fluctuations in the pH value.
In freshwater aquariums, the optimum pH value range for most fish and plants is between 6.5 and 7.2. However, special habitats such as Lake Malawi in Africa exhibit higher pH values of up to 9.0. Significant fluctuations and overly sharp decreases or increases in the pH value should be avoided at all costs. Therefore, the degree of acidity in the tank should be tested on a regular basis.
The pH-reagent from Tropic Marin®, especially developed for freshwater, allows the determination of the pH-value with the help of a finely tuned colour scale, which shows a range of 5.8 – 8.4 pH-units.
• Measurement range for freshwater: pH 5.8 – 8.4 • Accuracy: 0,2 – 0,3 • For determining the pH-value in freshwater aquaria • Quick and easy: just add 1 drop of reagent per measurement • Sufficient for approximately 100 applications • Allows the determination of the pH-value with the help of a finely tuned colour scale
How to use:
1. Shake the dropper bottle before use! 2. Rinse out the glass cuvette with tap water and then several times with aquarium water. 3. Fill the glass cuvette with exactly 5 ml of aquarium water using the dosing syringe. 4. Add 1 drop of pH test reagent, close the glass cuvette using the stopper and briefly shake the solution. 5. Place the glass cuvette on the white inner circles of the colour card and compare it to the surrounding colour fields. To do this, look into the open cuvette from above. 6. Read off the measured pH value under the relevant colour field. 7. Rinse out the glass cuvette and the syringe thoroughly with tap water after the measurement process.
How to correct unfavourable values
If the pH value is too high or too low in freshwater aquariums, partial water changes and periodic testing of the water quality can help to identify the reasons for the discrepancies.
Shelf life and storage6 months after opening. Store in a cool, dark place.
