Used to determine the concentration of magnesium (magnesium) in a marine aquarium reagent 3 spare cartridge Attention! Reagent 1 contains sodium hydroxide. Causes severe burns. Keep Regent locked up and out of reach of children. Wear protective gloves when working. If it gets into the eyes, wash them immediately with water, consult a doctor. In case of any nausea, seek medical help and take this manual with you An optimal concentration of magnesium is needed for marine invertebrates and algae. A perfect example is red calcareous algae. These consume large amounts of magnesium to build their skeleton. Natural seawater contains approximately 1300 mg/l. If we want to achieve optimal conditions in the marine aquarium, this concentration must be observed. You can conveniently and quickly determine the concentration of magnesium in a marine aquarium using the Sera magnesium test. The concentration of magnesium can be conveniently increased in the marine aquarium with sera magnesium plus. The magnesium level can be increased with sera marin COMPONENT 6 magnesium. Reagent consumption depends on the calcium level of the checked water. Store in a cool and dark place! Instructions for use: US Information for use An optimal magnesium level is required in a marine water aquarium in order for invertebrates and ornamental algae to thrive. Calcareous red algae are a perfect example. These ornamental algae require particularly 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 water 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 water aquarium by adding sera marin COMPONENT 6 magnesium. Directions for use: Shake reagent bottles well before using! Do not allow tested water to contact aquarium or pond water!  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 (included with the kit) 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 distributed. Possibly occurring cloudiness does not affect the test.  9. Add one level measurement spoon (included with the kit) 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, allowing air to 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. Close reagent bottles immediately after use and do not exchange caps. Store at room temperature and away from light. For testing ornamental fish aquariums and pond water only.   Store in a cool and dark place!

Since the emitted blue LED spectrum has been expanded using two different LEDs, the appropriate wavelengths of light for the photosynthesis process are ensured. It is also used to enhance color and enhance depth as additional lighting in the Malawi aquarium or as moonlight. The preferred combination is with LED X-Change Tube neutral brilliant white or LED X-Change Tube daylight sunrise. In combination with the sera LED Digital Dimmer, the light intensity of the sera LED X-Change Tube marine blue sunrise can be controlled. In addition, sunrise and sunset can even be simulated at individually set times.

Pond pumps for pond filters, brooks and fountains The sera pond pumps PP combine features important for modern pond keepers: The pumps are located maintenance friendly within a beautifully shaped basket with handle, which provides the pump with good standing area within the pond and protects it against coarse particles. The pumps are equipped with an optimized impeller, which largely prevents clogging and thus prolongs maintenance intervals. The asynchronous motor saves energy but is powerful at the same time. The pumps therefore provide higher pressure with larger pumped volumes and less energy consumption. The pumps are mainly designed for being placed within the pond, but can also be installed dry without the basket. All models are equipped with protection against running dry, which prevents the pump from overheating and switches it off. All sera pond pumps PP include a variable hose connector.

For the uncomplicated monitoring of marine water density The salinity (salt contents) can be deduced from the measured density. Since the salinity of marine water in an aquarium must be kept constant, the aquarium water should regularly be checked accordingly. The water to be tested is filled into a sufficiently tall water glass, and the scale of the immersed hydrometer is read off on according to its immersion depth.
