The JBL ProAqua Test pH 6.0-7.6 is a water test to analyse the optimal pH value in freshwater and saltwater aquariums.

With the ProAqua test, JBL offers the possibility of quickly and precisely determining the most important water values yourself in the home laboratory. Thanks to the enclosed, very detailed instructions for use with tips and advice, water testing is child's play. The contents of delivery include all required materials such as test reagents, dosing syringes, cuvettes, measuring spoons and colour cards. The test reagents can be purchased separately.

JBL ProAqua Test pH 6.0-7.6
Maintaining a suitable pH value as constant as possible is an important prerequisite for the well-being of all aquatic organisms. Above all, sudden fluctuations should be avoided. In addition, many substances dissolved in water are subject to changes depending on the pH. For example, the amount of CO2 that can be dissolved in water is directly related to the pH value. The pH value can, therefore, serve as a simple control variable for setting CO2 fertiliser systems, as long as there are no other acids (e.g. humic acids) in the water that influence the pH value. The optimal CO2 concentration for plants and harmless for fish is achieved at a pH of around 6.8-7.3. The carbonate hardness should not be below 4 ° dH. An exact pH measurement also for special applications such as fish farming, may be required. JBL PRO AQUATEST pH 6.0-7.6 is also used here. The optimal pH value for keeping most freshwater fish and plants is in the neutral range around 7.

However, there are also freshwater fish that need slightly acidic or alkaline water. For particularly precise measurements of the pH value, there is the JBL PRO AQUATEST pH 6.0-7.6 (also for checking the CO2 fertilisation) for freshwater aquariums and the JBL PRO AQUATEST pH 7.4 for freshwater aquariums -9.0. For sea water organisms, pH values around 8.2 can be regarded as optimal. Especially in saltwater aquariums with lower animals (invertebrates), the consumption of calcium bicarbonate can cause the pH value (and the carbonate hardness) to drop if a supply is not made regularly. When caring for fish from slightly alkaline freshwater, such as For example, Lake Malawi and Lake Tanganyika, values around 8-8.5 are recommended. For Koi and others, pH values between 7.5-8.5 can be regarded as optimal. In the garden pond, but especially in the aquarium, if there is a lack of CO2, especially algae, due to their rapid assimilation during photosynthesis, can consume the hydrogen carbonate in the water (biogenic decalcification) and thus drive the pH value to dangerous levels for fish (over 10).

Our expert Oliver Knott recommends:
With the pH value, an aquarium stands and falls - therefore this value should be kept in the eye!
