The sera aqua-test box guarantees reliable monitoring of all important
water parameters. A 250 ml (8.45 fl.oz.) bottle of sera aqua-dest has
been enclosed with the set for cleaning the measurement vials and for
the dilution of samples (phosphate- and copper-Test), when necessary.
Use only high-quality distilled water for refilling empty sera aqua-dest
bottles.
Please follow directions for use closely! Attention! Formation of a
curved surface (meniscus) can often be observed with watery liquids
in volume measuring devices, as the edge of the liquid surface is
slightly pulled up. Read off the volume at the lowest point of the liquid
surface in such cases. The lowest point of the meniscus must align
with the upper edge of the scale line (please see picture on page 90,
lowest point at, for instance, 5 ml). Use test reagents for the intended
purpose only! Do not allow tested water to contact aquarium or
pond water! Close reagent bottles immediately after use and do not
exchange caps. Keep locked up and out of the reach of children!
Store at room temperature and away from light. For testing ornamen-
tal fish aquariums and pond water only.

pH
n pH-Test (fresh and marine water)
Make sure the carbonate hardness is at least 5°dKH as
to achieve a stable pH value. Otherwise, there is dan-
ger of varying (suddenly sinking!) pH value. Therefore,
always check the carbonate hardness by means of the sera kH-Test
before adjusting the pH value. Use the sera water conditioners sera
KH/pH-plus for aquariums and sera pond bio balance for ponds for
increasing the carbonate hardness to at least 5°dKH.
Then adjust the pH value by either using sera KH/pH-plus for rais-
ing it or sera pH/KH-minus for lowering it. sera super peat (for
freshwater aquariums) can also lower and stabilize the pH value.

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 5 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add 4 drops of the reagent and shake until the liquid is evenly
distributed.
3. Compare the colors immediately. Place the vial on the chart and
compare from a position above under natural daylight. Avoid
direct sunlight.
4. Match the resulting color on the color chart and read off the pH
value.
5. Cleaning: Clean the vial thoroughly with tap water before and after
each test.
gH
n gH-Test (freshwater)
Most ornamental fish originate from countries where the
soil is poor in minerals. However, it is exactly the oppo-
site in many other areas around the world. Rain water
dissolves calcium and magnesium from the soil and consequently
creates hard water. With the sera gH-Test, you can quickly determine
the exact total hardness. Looking at the natural conditions helps
selecting the optimal fish stock for a community aquarium, and is a
precondition for successful breeding. High total hardness levels can
be lowered by mixing in R/O water. A combination of sera aquatan
and sera blackwater aquatan or filtering through sera super peat
will create soft water, as required for most South American fishes
(e.g. from the Amazon basin).
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 5 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add reagent drop by drop. Shake vial gently after every drop, until
the color changes from red via brown to an intense green.
3. The number of drops used from the reagent represents the exist-
ing total hardness (in °dGH). E.g., 5 drops = 5°dGH.
4. Cleaning: Clean the vial thoroughly with tap water before and
after each test.
kH
n kH-Test (fresh and marine water)
Carbonate hardness (KH) stabilizes the pH value. It
buffers variations as caused by biological breakdown
processes in aquariums and ponds, and by plants tak-
ing up carbon dioxide. A low carbonate hardness (below 5°dKH)
causes a strongly varying (suddenly sinking!) pH value. In community
aquariums, KH values between 5 and 10°dKH ensure a stable pH and
vigorous plant growth. Cichlids from Lake Malawi and Tanganyika
prefer higher KH values. Ideal KH for marine water aquariums is
between 8 and 12°dKH. By using sera KH/pH-plus (for freshwater),
sera marin COMPONENT 2 Ca pH-Buffer (for marine water) or sera
pond bio balance (for ponds), you can easily achieve the desired KH
level. If you want to lower the pH value of the water, you can lower
high carbonate hardness (e.g. more than 21°dKH in a community
aquarium) with sera super peat (for fresh water aquariums) if nec-
essary.
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 5 ml mark (please see page 90, fig. “volume
reading in sera test vials”). Dry the vial on the outside.
2. Add reagent drop by drop. Shake vial gently after every drop, until
the color changes from blue via green to clear yellow.
3. The number of drops used from the reagent corresponds to the
existing carbonate hardness (in °dKH). E.g., 5 drops = 5°dKH.
4.
Cleaning: Clean the vial thoroughly with tap water before and after
each test.

Reagent 3: Danger! Contains sodium hy-
pochlorite, solution 1.6% Cl active, sodium
hydroxide. Causes severe skin burns and
eye damage. Warning! Do not use together
with other products. May release dangerous
gases (chlorine). If medical advice is needed,
have product container or label at hand.
Keep out of reach of children. Do not breathe vapours. Wear
protective gloves, eye protection. IF SWALLOWED: Rinse mouth.
Do NOT induce vomiting. IF ON SKIN (or hair): Take off immedi-
ately all contaminated clothing. Rinse skin with water. IF IN-
HALED: Remove person to fresh air and keep comfortable for
breathing. 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.
High ammonium levels indicate a disturbed or not fully developed
bacterial activity in the filter. Ammonia (NH
3
) formed from ammonium
(NH
4
) in case of pH values above 7 is especially dangerous. Even
ammonia values of 0.02 mg/l lead to gill damages in the long term.
Therefore you should always check the pH value in addition to the
NH
4
level. Evaluation and judgment of the meas ured values is effect-
ed using the chart below.
sera toxivec immediately lowers the ammonia value in acute cases.
Additionally, the biological filter activity should be improved by using
sera bio nitrivec (freshwater), sera pond bio nitrivec (ponds) or
sera marin bio reefclear (marine water), respectively. Regular par-
tial water changes prevent too high water pollution.
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 (freshwater) or the 5 ml mark
(marine water) (please see page 90, fig. “volume reading in sera
test vials”). Dry the vial on the outside.
2. Add 6 drops of reagent 1 and shake until the liquid is evenly
distributed.
3. Add 6 drops of reagent 2 and shake the same manner.
4. Add 6 drops of reagent 3 and shake the same manner.
