n nitrite-Test (fresh and marine water)
Reagent 1: Warning! Contains 11.6% hy-
drochloric acid. Causes skin irritation.
Causes serious eye irritation. May cause
respiratory irritation. If medical advice is
needed, have product container or label at
hand. Keep out of reach of children. IF ON
SKIN: Wash with plenty of water. If skin irri-
tation occurs: Get medical advice. 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.
Nitrite is formed as an intermediate product during the breakdown
of fish waste. Too high nitrite levels endanger the fish. Nitrite is formed
from ammonium and is converted into nitrate by bacteria in a func-
tioning filter or one that has been activated with sera bio nitrivec.
Therefore also ammonium and nitrate should be checked regularly,
using the sera ammonium/ammonia-Test kit and the sera nitrate-
Test kit. We recommend using sera aquatan and sera bio nitrivec
in freshwater aquariums, sera aquatan and sera marin bio reefclear
in marine aquariums, and sera KOI PROTECT and sera pond bio
nitrivec in ponds, with every water change.
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 5 drops of reagent 1 into the vial and shake the vial until the
liquid is evenly distributed.
3. Add 5 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. Cleaning: Clean the vial thoroughly with tap water before and
after each test.

n nitrate-Test (fresh and marine water)
Reagent 3: Warning! Very toxic to aquatic
life with long lasting effects. Avoid release
to the environment. Collect spillage. Dis pose
of container to household waste.
Monitor nitrate easily, quickly and reliably with the sera nitrate-Test
kit.
Algae thrive whereas fish and plants become stunted if the nitrate
level is above 50 mg/l. We therefore recommend you to stay informed
about the nitrate level in your aquarium or pond. You can lower nitrate
levels by adding rapidly growing plants, using a slow flux filter with
sera siporax Professional and/or carry out water changes more
frequently (provided your tap water is low in nitrate).
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 6 drops reagent 1 and shake the vial until the liquid is evenly
distributed.
3. Add 6 drops reagent 2 and shake the same manner.
4. Add one measurement spoon (red) reagent 3 into the vial.
5. Close with the cover and shake vigorously for precisely 15 seconds.
6. Open the vial and add 6 drops reagent 4. Shake the vial until the
liquid is evenly distributed.
7. Compare the colors after 5 minutes: Place the vial on the color
chart and compare the colors from a position above under natu-

n phosphate-Test (fresh and marine water)
Reagent 1 and reagent 2: Warning! Causes
skin irritation. Causes serious eye irritation.
If medical advice is needed, have product
container or label at hand. Keep out of reach
of children. Wear protective gloves, eye
protection. IF ON SKIN: Wash with plenty of
water. If skin irritation occurs: Get medical
advice. IF IN EYES: Rinse cautiously with water for several min-
utes. Remove contact lenses, if present and easy to do. Continue
rinsing. If eye irritation persists: Get medical advice. Dispose of
container to household waste.
In natural unpolluted water, we can find phosphate levels of up to
1.0 mg/l. In aquariums or ponds, concentrations of 10.0 mg/l or more
are usual. They are the result of too many fish, foods with high phos-
phate levels and plant fertilizers containing phosphate. A high phos-
phate level with high nitrate values leads to algae bloom. Therefore,
checking the phosphate level in your aquarium or pond at regular
intervals is important. Freshwater aquariums and ponds should not
have more than 1.0 mg/l of phosphate. Marine aquariums should not
have more than 0.1 mg/l of phosphate. Frequent water changes
(approx. 10 – 30%, once a week), introducing fast growing plants are
methods of reducing phosphate levels. Additionally, sera
phosvec·clear and/or sera phosvec Granulat (in freshwater aquar-
iums) and sera pond phosvec (in ponds) are suitable.
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. “vol-
ume reading in sera test vials”). Dry the vial on the outside.
2. Add 6 drops of reagent 1 into the vial and shake the vial until the
liquid is evenly distributed.
3. Add 6 drops of reagent 2 into the vial and shake the same manner.
4. Add one heaping measurement spoon (white) of reagent 3. Close
vial with cover and shake. Then, remove the cover.
5. Compare the colors after 5 minutes. Place the vial on the color
chart and compare the colors from a position above at natural
daylight. Avoid direct sunlight.
6. The water is extremely low in phosphate or phosphate-free if the
result does not show any blue color. If the result shows dark blue
color, the test sample contains more than 2.0 mg/l of phosphate.
Repeat the test with a diluted sample. Further dilution may be
required with repeated tests, if the result cannot be matched with
the color on the chart.
7. To do so, rinse the vial carefully with the water to be tested and
fill up to the 5 ml mark with this water. 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 described in items 2. to 5.
