PH test 3.0-10.0 REFIL ProAqua - JBL

JBL ProAquaTest pH 3-10

Maintaining a proper pH value is essential to maintain the well-being of all aquatic organisms. In particular, sudden fluctuations should be avoided. For example, the amount of CO2 to dissolve in water is directly proportional to the pH value. The pH value can therefore act as a simple control variable for the regulation of fertilization systems with CO2, provided that there are no other acids in the water that influence the pH value (e.g. wet acids). The optimum concentration of CO2 for plants and harmless for fish is reached at a pH value of about 6,8-7,3. Carbonate hardness should not be less than 4° dH. Here it is also used JBL ProAquaTest pH 6,0-7,6. The optimal pH value for most freshwater fish and plants is around 7.

However, there are also freshwater fish that require slightly acidic water or alkaline. For precise measurements of the pH value, there is the JBL ProAquaTest pH 6.0-7.6 (also for the control of fertilization with CO2) for fresh water aquariums, adapted to its pH ranges, and JBL ProAquaTest pH 7.4-9.0 for seawater aquariums and ponds. For marine organisms, the pH values to be considered optimal are around 8.2. Especially in marine aquariums with invertebrates, calcium bicarbonate consumption can decrease the pH value (and carbonate hardness). When taking care of fish from fresh water slightly alkaline, e.g. Lake Malawi or Lake Tanganyika, we recommend pH values around 8-8.5. For koi carps and other fish, the optimal pH values are between 7.5-8.5. In the garden pond, but especially in aquariums, in case of CO2 deficiency, algae in particular can consume hydrogencarbonate present in the water through their rapid assimilation during photosynthesis (biogenic decalcification) and therefore bring the pH value to levels such as are dangerous for fishes (over 10).
