Cl
n chlorine-Test (fresh and marine water)
In many areas, chlorine is added to tap water as a dis-
infectant. Chlorine destroys the filter bacteria and is very
corrosive towards the fish’s gills and mucous mem-
branes. You can easily and reliably check for chlorine in the tap water
by using the sera chlorine-Test. sera toxivec immediately removes
harmful chlorine and chloramine. sera aquatan makes the water fish
friendly; sera bio nitrivec activates biological filtration with useful
bio cultures.
Directions for use: Shake reagent bottle well before using!
1. Rinse the measurement vial several times with the water to be
tested, then fill to the 10 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add 8 drops reagent and shake the vial until the liquid is evenly
distributed.
3. Compare the colors immediately: Place the vial on a white surface
and compare the colors from a position above under natural
daylight. Avoid direct sunlight.
4. If no color change occurs, the water is chlorine-free. Harmful
chlorine levels from 0.02 mg/l will result in yellow coloration, with
higher chlorine levels the color becomes reddish.
5. Cleaning: Clean the vial thoroughly with tap water before and
after each test.
The following tests are not included in the sera aqua-test box. They
can be purchased separately from your specialty retailer.

and other ignition sources. No smoking.
Keep container tightly closed. Dispose of

Aquatic plants are living beings that require correct lighting and,
above all, regular fertilization with all important nutrients for their
healthy growth. A combination of sera floredepot (gravel substrate),
sera florena (liquid complete iron fertilizer), sera CO
2
-Start, sera
florenette (fertilizer tablets) and the sera flore CO
2
fertilization
system ensures lush plant growth and stable water conditions in
your aquarium. sera flore 4 plant should be used additionally in case
of densely planted (Dutch style) aquariums with few fish.
Directions for use: Shake indicator solution bottle well before using!
1. Remove the pyramid-shaped cap and fill it with the aquarium
water (approx. 1.5 ml), just below the edge.
2. Add 3 – 4 drops of indicator solution, and put the pyramid-shaped
cap back on.
3. Invert the testing device and mount it vertically to the aquarium
glass using the provided suction cup. Follow this procedure care-
fully, otherwise it will lead to inaccurate results and eventually
cause damage to the testing device!
Please note: Ensure the hollow space under the device is only
partly filled with water.
4. Attach the color decal to the outside glass of the aquarium. Close
to the testing device, to compare the ongoing test colors.
5. After a prolonged period, the color in the testing device will fade.
When this happens, refill the indicator solution and aquarium
water, as described above 1 to 3. Clean the testing device.
6. If you have difficulty removing the cap of the testing device, it
means the silicon grease on the O-ring has dried up. In this case,
carefully remove the cap with a small screwdriver and grease the
O-ring with silicone.

Important: The sera CO

in aquarium water. Reaction time may have a delay of 30 to
60 minutes. If the water level in the testing device changes rapidly,
it means the cap is not tightly fitted or the O-ring has become brittle
and must be replaced. Please check and correct.
Mg
n magnesium-Test (marine water)
Reagent 1: Danger!
Contains sodium hy-
droxide. Harmful if
swallowed. Causes
severe skin burns and
eye damage. If medi-
cal advice is needed,
have product container or label at hand. Keep out of reach of
children. Wear protective gloves, eye protection. IF SWAL-
LOWED: Rinse mouth. Do NOT induce vomiting. IF ON SKIN
(or hair): Take off immediately all contaminated clothing. Rinse
skin with water. IF IN EYES: Rinse cautiously with water for
several minutes. Remove contact lenses, if present and easy to
do. Continue rinsing. Immediately call a doctor. Dispose of
container to household waste.
An optimal magnesium level is required in a marine aquarium in order
for invertebrates and ornamental algae to thrive. Calcareous red
algae are a perfect example. These ornamental algae require par-
ticularly much magnesium, as they integrate this element into their
skeleton. Natural marine water contains about 1,300 mg/l. This level
should also be maintained in an optimal marine aquarium. The sera
magnesium-Test allows you to monitor the magnesium level in your
aquarium quickly and easily. It is even easier if you have gathered
testing experience by using the sera calcium-Test. You can easily
increase the magnesium level in your marine aquarium by adding
sera marin COMPONENT 6 magnesium.
Directions for use: Shake reagent bottles well before using!
1. Rinse the measurement vial several times with the water to be
tested, then empty the vial. Dry the vial on the outside.
2. Rinse the syringe several times with the water to be tested, then
fill 2 ml of it into the vial, using the syringe.
3. Add 6 drops reagent 1 and shake the vial until the liquid is evenly
distributed. Possibly occurring cloudiness does not affect the test.
4. Add one level measurement spoon (white) reagent 2 into the vial
and gently whirl the vial (do not shake) until the powder has dis-
solved.
5. Add reagent 3 drop by drop while counting the drops, release
the reagent bottle from finger pressure after every 5 drops, allow-
ing air to be drawn into the bottle. Shake vial after every drop
until the color turns from pink into clear blue (not violet) and
remains stable for at least 30 seconds whilst whirling the vial
occasionally. Write down the number of drops used.
6. Empty the measurement vial, rinse it carefully with tap water and
then several times with the water to be tested, then empty the
vial. Dry the vial on the outside.
7. Take up 2 ml of the water to be tested into the syringe and fill it
into the vial.
8. Add 6 drops reagent 4 and shake the vial until the liquid is
evenly distributed. Possibly occurring cloudiness does not affect
the test.
9. Add one level measurement spoon (white) reagent 5 into the vial
and gently whirl the vial (do not shake) until the powder has
dissolved.
10. Add reagent 3 drop by drop while counting the drops, release
the reagent bottle from finger pressure after every 5 drops, allow-
ing air to be drawn into the bottle. Shake vial after every drop
until the color turns from red into grass green and remains stable
for at least 30 seconds whilst whirling the vial occasionally.
Attention – you will need considerably more drops for this
measurement than for the first measurement!
11. Subtract the number of drops required for the first measurement
from the result of the second measurement. Multiply the remain-
ing number of drops by 60 to get the magnesium level in mg/l.
Example: The first measurement required 4 drops, the second
measurement 24 drops. If you subtract the first measurement
result from the second one, 20 drops will remain. 20 drops mul-
tiplied by 60 makes 1,200 mg/l magnesium.
12. Cleaning: Clean vial and syringe thoroughly with tap water before
and after each test.
