pH Test Set 3.0 – 10.0
Features
The JBL pH test set 3.0-10 is an easy-to-use, quick test for general guidance and control of the pH level in
freshwater and saltwater and in the garden pond, covering the wide pH-range 3.0 to 10.
Why test the pH level?
The well-being of fish, invertebrates and the growth of aquatic plants depend to a large extent on the pH level
being kept as constant as possible. Many substances dissolved in water are also liable to changes caused by the
pH level. Fluctuations in the pH level, in particular, ought to be avoided. The pH level most conducive for keeping
the majority of freshwater fish and plants is in the neutral range around 7. A pH level of around 7.9 -8.5 should be
maintained in marine aquariums. Levels of 7.5 - 8.5 are ideal for garden ponds.
For precise measurements of the pH level in the range of 6.0 to 7.6, the range which is important for freshwater
aquariums (especially for the control of CO
measurements of the pH level in marine water aquariums and garden ponds use the JBL pH test set 7.4-9.0.
What to do in the event of deviations in the pH level
Freshwater aquariums:
pH levels can be reduced with JBL pH-Minus. However, a more convenient way of adjusting the pH level in
freshwater is provided by the JBL PROFLORA CO
with vital CO at the same time.

pH levels can be increased by increasing the carbonate hardness with JBL AquaDur plus or pH-Plus.
