How can it be removed?
Large amounts of copper which have collected in the ground-covering material of the aquarium as a result of
the use of copper-containing preparations can only be removed by clearing out and throwing away all of the
ground-covering material.
The regular use of a water conditioner which binds heavy metals, such as JBL Biotopol, offers increased
safety when copper is introduced to the aquarium from domestic plumbing or the use of rainwater. In order to
avoid extreme levels we recommend running the tap water for a few minutes before taking water from the mains.
In the case of copper guttering, water should only be collected after it has been raining for about one hour.
On the use of water conditioners, it should be mentioned that these do not remove heavy metals (copper etc.)
from the water, rather the heavy metals are enclosed in a protective “coating” and are no longer harmful to sh.
In the course of time they are then used up by the plants etc. as trace elements. If actual removal is important,
the water should be ltered through efcient activated carbon (e.g. JBL Carbomec activ) about one hour after
the water conditioner has been used. The activated carbon should be removed from the lter the following day
and disposed of. The heavy metals which the water conditioner has “coated” are absorbed by the activated
carbon and therefore removed when the carbon is taken out of the lter. Heavy metals which have not been
“coated” in the manner described above cannot be removed by activated carbon.
What is measured?
The copper test only measures copper which is dissolved in water. Copper deposits in the ground-covering
material (as mentioned above) are not measured by the test.
Instructions:
1. Repeatedly rinse both test jars with the water to be tested.
2. Use the enclosed syringe to ll each of the test jars with 5 ml of sample water.
3. Add 5 drops of reagent 1 to one o f t h e t w o t e s t j a r s , s h a ke b r i e y t o m i x , t h e n a d d 5 d r o p s o f r e a g e n t 2 a n d m i x a g a i n .
4. Allow to stand until the full colouring develops, 10 minutes for tests on freshwater and 15 minutes for tests on
saltwater.
5. Place both test jars in the grey comparator block: the jar with the added reagent at the smooth end of the
comparator block, the jar with untreated sample water (blank sample) at the notched end of the comparator block.
6. Position the comparator block on the colour chart so that the jar containing untreated water is over the
coloured sections of the chart, whilst the jar with added reagent is over the blank sections of the colour chart.
Move the comparator block with the two test jars backwards and forwards on the colour chart, until the colour
of the sample treated with reagent matches the colour under the blank sample as closely as possible.
7. Read the copper content in the notch of the comparator block.
The instructions are repeated in a series of simple diagrams on the reverse of the colour chart.

Calcium Test Set Ca
Features:
The JBL calcium test set Ca is a quick and easy to use test to measure the calcium content of sea water.
Why test?
Invertebrates (corals, shellsh etc.) and calcareous algae in sea water require sufcient levels of calcium for
healthy growth. The natural calcium level of the sea is 390-440 mg/l. In order that the organism can make
the best use of the calcium, hydrogen carbonate must also be present in the water in the correct proportions.
