lush plant growth and stable water conditions in your aquarium.
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 carefully, other-
wise 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.

An optimal magnesium level is required in a saltwater aquarium in order for
invertebrates and ornamental algae to thrive. Calcareous red algae are a per-
fect example. These ornamental algae require particularly much magne-
sium, as they integrate this element into their skeleton. Natural saltwater
contains about 1,300 mg/l. This level should also be maintained in an optimal
saltwater 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 saltwater aquarium by adding
sera magnesium plus.
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 distrib-
uted. 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 dissolved.
5. 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 into 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 distrib-
uted. 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.

be drawn into the bottle. Shake vial after every drop until the color turns
from red into 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 remaining 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 multiplied by 60 makes 1,200 mg/l magnesium.
12. Cleaning: Clean vial and syringe thoroughly with tap water before and
after each test.

2. Add 6 drops of reagent 1.
3. Next add 6 drops of reagent 2, place the cover on the vial immediately
(ensure there are no air bubbles in the water) and then shake. Remove
the cover.
4. Compare the color of the precipitate (flakes) to the color chart to deter-
mine the oxygen level. Place the vial on the color chart and compare the
colors from a position above under natural daylight. Avoid direct sun-
light.
5. Cleaning: Clean vial and cover thoroughly with tap water before and after
each test.
