It measures magnesium levels in precise 30 mg/L color steps, unaffected by calcium or strontium interference, ensuring optimal coral and algae growth by maintaining balanced magnesium concentrations essential for photosynthesis and reef vitality. ## Description Product Description Salifert Magnesium Profit-Test 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 Profit-Test is easy to use and accurate with measurements in steps of 30 mg/L. Results are not affected by strontium and calcium interference. Can be used for marine water only. Calcium and strontium will not interfere when their total concentration is between 200 and 650 ppm. This is mostly the case. Up to 50 tests.Warning!Keep out of reach of children. Not for consumption. Directions See Directions Before Use. Review: Seems to work well - I bought this to replace another magnesium test kit that was throwing up some weird results that just couldn’t be correct as magnesium only gets there if you put it there and would tend to drop over time so should just go up on it’s own. This kit works in the same way where you prepare a sample of tank water using the chemicals provided and then dripping in to the solution another chemical from a syringe until the colour of the water sample changes, the amount of fluid left in the syringe in ml is then read off a table to give the magnesium reading. It is a bit fiddly but the whole process actually takes less than 5 minutes, if that. The results of this kit are giving results that are what I would expect so I would trust the results of the kit.
