Instructions:
1. Repeatedly rinse both test jars with the aquarium water to be
tested.
2. Use the enclosed syringe to fill each of the test jars with 5 ml of
sample water.
3. Add 3 drops of 6.0 - 7.6 reagent to one of the test jars and mix by
agitating.
4. Place both test jars into the comparator block: the jar with added
reagent into the smooth end of the comparator block, the jar with
the untreated test water (blank sample) into the notched end of
the comparator block.
5. Move the comparator block together with the jars side to side
over the colour chart with the notch pointing to the levels until
the colour of the sample with added reagent matches the colour
of the blank sample.
6. Read the pH level in the notch of the comparator.
See the JBL brochure "What - Why - How" No. 2 for more details on
