JBL TESTLAB Bedienungsanleitung Seite 26

Instructions:
1. Repeatedly rinse both test jars with the water to be tested.
2. Use the enclosed syringe to fill each of the test jars with 5 ml of sample water.
3. Add 5 drops of Fe-reagent to one of the test jars and mix by agitating. Allow to settle for 5
minutes.
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 from side to side over the colour chart,
with the notched side of the block facing the scale, until the colour of the sample with added
reagent matches the colour of the blank sample.
6. Read the iron content in the notch of the comparator.
Please observe the safety notice on the reagent bottle!
Note:
If you decide to use the JBL Ammonium test Set at the same time, make sure not to mix up the
test jars of both sets. Traces of the ammonium test left inside the test jar may lead to incorrect
high readings in the iron test.
See the JBL brochure "What, Why, How" No.2 for more details on the significance of iron and
other trace elements for a thriving underwater aquarium garden.
Our tip for the ecologically-minded users:
All reagents for the JBL Test Sets are also available in convenient and reasonably priced refill
packs.
