Iron Test Set Fe - JBL TESTLAB Manual

test, i.e. it should be below 0.25 mg/l. Most importantly, garden fertilizers from the area surrounding the pond
must be prevented from entering the water. Pollen deposited in the spring is another source of phosphate in
garden ponds that should not be underestimated.
Remedial action:
Koi pond:
• Binding with JBL PhosEx Pond Filter or JBL PhosEx Pond Direct
• Careful feeding that meets the nutritional needs of the animals
• Preventing fertilizers from the surrounding area from entering the pond
Note:
When filling your koi pond with mains water, you should also bear in mind that some waterworks add phosphates
to the mains water in order to prevent lime build-up and corrosion in the pipe system. This can already lead to
an initial contamination of approx. 2 mg/l PO
Instructions:
1. Rinse two test jars several times 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 the reagents to one of the two test jars as follows:
a) A large measuring spoon (broad end of the enclosed double-ended spoon) reagent 1, close with the lid
and shake until dissolved
b) 5 drops of reagent 2, shake and 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 backwards and forwards on the colour chart, with the
notched side of the block facing the scale, until the colour of the sample treated with reagent matches the
colour under the blank sample as closely as possible.
6. Read the phosphate content in the notch of the comparator block. The graduation of colours from green to
red provided on the colour chart enables you to read the measured value easily.
In the event that the colour of your test sample is darker than the colours of the chart, dilute the sample with
distilled or phosphate-free water and measure again.
Depending on the dilution, the result must be multiplied as follows to determine the actual phosphate content:
2.5 ml sample + 2.5ml dist. water: result x 2
1 ml sample + 4 ml dist. water: result x 5
The instructions are repeated in a series of simple diagrams on the reverse of the colour chart.
Warning and safety notices concerning reagent 2:

Iron Test Set Fe

Special features:
The JBL iron test set Fe is for the measurement and routine control of the iron content in freshwater and marine
aquariums as well as in garden ponds within the range 0.05-1.5 mg/litre (ppm). Using the compensation method
specially developed by JBL, precise and reliable results can be obtained even in moderately discoloured water,
e.g. caused by peat filters and disease treatment.
Why test?
Besides an adequate supply of CO
