8. Compare the colors with the color chart once again. Please do
not forget to read the value given in the line “5 ml + 5 ml!”
9. If the resulting color still is dark blue, the phosphate level is
4.0 mg/l or more. In this case, you should repeat the measure-
ment choosing the dilution “2 ml + 8 ml.” Read off the value in
the corresponding line. By doing so, phosphate values up to
10.0 mg/l can be monitored.
10. Cleaning: Clean vial and cover thoroughly with tap water before
and after each test.

Reagent 2: Warning! Contains sodium
thioglycolate. May cause an allergic skin
reaction. If medical advice is needed, have
product container or label at hand. Keep
out of reach of children. Avoid breathing
vapours. Wear protective gloves. IF ON
SKIN: Wash with plenty of water. If skin ir-
ritation or rash occurs: Get medical advice. Dispose of container
to household waste.
Iron is one of the many important nutrients for all aquatic plants.
Inadequate iron level affects plants adversely. However, high iron
content in the water harms the fish. Not every type of iron is usable by
the plants. Thus, iron from tap water is disadvantageous. Discolored
yellow leaves of aquatic plants are a definite symptom of iron defi-
ciency. Iron values of above 0.5 mg/l are harmful for fish and plants.
The liquid fertilizer sera florena (complete iron fertilizer) and the
fertilizer tablets sera florenette ensure an ideal nutrient supply for
the plants. The ideal iron concentration immediately after fertilization
is 0.25 0.5 mg/l. Please note that the dosage stated in the directions
for use is merely a directional value. The actual fertilization rhythm
depends on many factors, such as the number and types of aquatic
plants and the CO
2
supply. We therefore recommend using the sera
iron-Test (Fe) for monitoring the nutrient level.
Directions for use: Shake reagent 2 well before using!
1. Rinse the measurement vial several times with the water to be
tested, then fill to the 5 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add 2 heaping measurement spoons (white) of reagent 1, then
shake lightly. The reagent does not dissolve completely.
3. Add 5 drops of reagent 2, then shake the vial lightly until the liquid
is evenly distributed.
4. Compare the colors after 10 minutes. Place the vial on the color
chart and compare the colors from a position above at natural
daylight. Avoid direct sunlight.
5. Cleaning: Clean the vial thoroughly with tap water before and
after each test.

out of reach of children.
Keep away from heat,
hot surfaces, sparks,
openamesandother
ignition sources. No smoking. Keep container tightly closed.
Dispose of container to household waste. Reagent 2: Warning!
Causes serious eye irritation. If medical advice is needed, have
product container or label at hand. Keep out of reach of children.
Wear eye protection. IF IN EYES: Rinse cautiously with water
for several minutes. Remove contact lenses, if present and easy
to do. Continue rinsing. If eye irritation persists: Get medical
advice. Dispose of container to household waste.
Copper is often the reason for inexplicable dying of fish. Copper pipes,
medications or algicides are sources of copper ions. Even low copper
concentrations are harmful for aquatic organisms (please see chart).
Therefore the copper level should be measured regularly. Neutralization
of copper ions is achieved with sera aquatan or sera toxivec.
Directions for use: Shake reagent bottles 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 7 drops of reagent 1 into the vial and shake the vial until the
liquid is evenly dis tribut ed.
3. Add 7 drops of reagent 2 into the vial and shake the same
manner.
4. Compare the colors after 5 minutes. Place the vial on the color
chart and compare the colors from a position above under natu-
ral daylight. Avoid direct sunlight.
5. Is the color dark blue, the sample contains more than 1 mg/l
copper. Repeat the measurement with a diluted sample.
6. To do so, rinse the vial carefully with the water to be tested and
fill to the 5 ml mark. Top up to the 10 ml mark with distilled water
(please see page 90, fig. “volume reading in sera test vials”). Use
sera aqua-dest or a pharmaceutical grade distilled water. Repeat
the test as mentioned with points 2. to 4.
7. Compare the colors once again with the color chart. Please do
not forget to read the value given in the line “5 ml + 5 ml!”
8. Cleaning: Clean the vial thoroughly with tap water before and
after each test.

Ca
n calcium-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.
Ornamental algae, corals and other invertebrates permanently require
sufficient calcium amounts for their healthy growth. The calcium level
in natural marine water is about 410 mg/l. Ideal calcium levels in
marine water aquariums are between 400 and 450 mg/l.
You should therefore regularly check the calcium level in your marine
aquarium. This can quickly and easily be done with the sera calcium-
Test kit (Ca). sera marin COMPONENT 1 + 2 safely increase the
calcium level in your marine aquarium.
Directions for use: Shake reagent bottles well before using!
1. Rinse the measurement vial several times with the water to be
tested, then fill to the 5 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add 8 drops of reagent 1. Shake the vial until the liquid is evenly
distributed. A possible cloudiness does not affect the accuracy
of the test.
3. Add a level-filled measurement spoon (white) of reagent 2, whirl
the vial gently (do not shake) until the powder has dissolved.
4. Add reagent 3 drop by drop while counting the drops, release the
reagent bottle from finger pressure after every 5 drops, allowing
air to be drawn into the bottle. Shake vial after every drop until
the color turns from pink via violet into blue and remains stable
for at least 30 seconds whilst whirling the vial occasionally.
Reagent 3 refills (15 ml/0.5 fl.oz.) are available separately.
5. The number of drops used from reagent 3, multiplied by 20 is the
calcium level in mg/l, e.g., 15 drops of reagent times 20 = 300 mg
calcium per liter.
6. Cleaning: Clean the vial thoroughly with tap water before and
after each test.
