Product description
The JBL pH Test-Set Special is designed for the accurate measurement and routine control of the pH-value in freshwater within the relevant range of 6.0 -7.6, and above all for the control and the adjustment of CO2-fertilization with the JBL PROFLORA CO2-system. The compensation method developed specially by JBL allows precise and reliable results to be obtained even in moderately discoloured aquarium water, e.g. caused by peat filters and disease treatment.
Problem solutions
The pH-level indicates the acidity of the water. The higher the pH-level, the less acid is in the water, the proportion of alkali is higher (the opposite of acids). The lower the pH-level, the more acid the water contains. In aquariums and ponds the following levels are desirable.

Community aquariums: pH: 6,5 - 7,5
Ponds: pH: 6,5-7,5
Lake Malawi and Tanganyika aquariums: pH: 7,5-8,5

Saltwater (marine) aquariums: pH: If the pH-level is above the levels given, it should be gradually reduced. Before the pH-level is reduced, the pH-stability of the water must be checked! In order to do this, the carbonate hardness should be measured. In freshwater it should be between 4° and 10° German carbonate hardness (GCH) and in saltwater between 7° and 12° GCH. If the CH is below the levels mentioned, the pH-level is not stabilised and any alteration in the pH-level may lead to a sudden plunge in the CH! Instructions on how to adjust CH levels are given in the CH test.
The pH-level in the freshwater aquarium can be reduced by:
1. The addition of JBL Aquacid (pH-reducer)
2. The addition of CO2 (JBL Proflora CO2-System)
3. Filtering through JBL Tormec (black turf granulate)"
