JBL ProAquaTest CO2 / pH Permanent, Test

The JBL ProAqua Test CO2-pH Permanent is a long-term test for fertiliser control in freshwater aquariums.

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. In the garden pond, but especially in the aquarium, if there is a lack of CO2, algae especially, 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). Thanks to the JBL ProAquaTest Co2-pH Permanent, the pH value and the carbon content can be permanently measured and quickly read.

Application: Put the reagent in the long-term test device and attach it to the aquarium panel using suction cups. Compare the reagent colour with the colour scale sticker and read the value.
