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)
The pH-level in the saltwater aquarium can be reduced by:
1) The monitored addition of CO2 (JBL Proflora CO2-System Profi 3)
The pH-level in the freshwater aquarium can be increased by:
1) The addition of JBL Aquakal (raises pH-level)
2) Reduction in CO2-supply
The pH-level in the saltwater aquarium can be increased by:
1) The addition of JBL CalciuMarin (which stabilises the pH-level)
