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
plants constantly consume iron and other trace elements, which only keep in the water for a limited period even
when bonded to so-called chelating agents (usually found in modern fertilizers, e.g. in JBL Ferropol), the iron
content must be monitored regularly with the JBL iron test set Fe and replenished if necessary. A concentration
of 0.1-0.2 mg/litre (ppm) is normally adequate for good plant growth, for very plant intensive aquariums values
up to 0.5 mg/l (ppm) can be useful. The JBL iron test set Fe can also be used to measure the iron content in tap
water (normally iron-free) or in natural waters as well as in garden ponds. Levels between 0.002 and 0.05 mg/l are
recommended in marine aquariums.
Remedy:
Iron content too low: fertilize with JBL Ferropol and Ferropol 24, JBL ProScape Fe +Microelements.
Iron content too high: change part of the water or filter with JBL Carbomec activ.
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 shaking. 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 iron content in the notch of the comparator.
Note:
If you decide to use the JBL ammonium test set at the same time, make sure not to mix up the measuring vessels
of both sets. Traces of the ammonium test left inside the measuring vessel may lead to incorrect high readings in
the iron test.
The instructions are repeated in a series of simple diagrams on the reverse of the colour chart.
Our tip for the environmentally-friendly users:
All reagents for JBL test sets are available from your retailer as reasonably-priced refill packs!

KH Test Set
Features
The JBL KH Test Set is an easy to use quick-test for determining the carbonate hardness or the acid binding
capacity of freshwater, saltwater and garden pond water.
Why test?
Depending on origin and consistency of the subsoil, water may contain varying quantities of alkaline earth salts.
Owing to the effects of CO
, aquatic vegetation needs iron and trace elements. Since healthy aquatic
2
, a large proportion of these salts is represented by hydrogen carbonates. By definition,
