Salifert Magnesium Profi Test Kit

Magnesium is present in natural sea water in a fairly high concentration (1350 - 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive.

  • Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the formation of calcium carbonate which can absorb many important trace elements within the aquarium.

  • Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth by making it possible to maintain correct calcium and alkalinity figures.

  • Magnesium is depleted by algae growth and also by the use of excessive kalkwasser or by going far beyond natural calcium, alkalinity and pH values.

  • The Salifert Magnesium Profi-Test is easy to use and accurate with measurements in steps of 30 mg/L.

  • Results are not affected by strontium and calcium interference.

  • Sufficient for 50 tests.

A great versatile watch
Color: black/black
This is a great watch. I wear a Rolex GMT daily, but wear this at the gym, at fencing practice, holding power equipment , hammering and other activities. Runs fine, keeps good time, easy to read. Like the 24 hour dial. Sometimes I just wear it because I like it.

Good watch, not incredibly durable for everyday use.
Color: silver/brown
A nice watch, the date feature and the glow in the dark were quite helpful. It lasted be about 6 months of regular use. Unfortunately it stopped keeping time (intermittent freezing) and the second hand fell off, I'm kinda disappointed with its durability. Unsure of the initial cause, I guess I hit something with my wrist.
