Product description
The JBL pH Test-Set 7,4 - 9,0 can be used for exact measurements and routine monitoring of pH levels in salt water and slightly alkaline fresh water, as required by fish from Lake Malawi for example. Thanks to the compensation procedure developed by JBL, precise and reliable results can also be obtained in lightly discoloured water e.g. during the treatment of diseases.
Note the warning on the reagent bottle!
Keep out of reach of children!
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)
The pH-level in the garden pond can be reduced by:
1. The addition of JBL Acilon (pH-reducer)
2. Filtering through JBL HumoPond (black turf granulate)"
