The Salifert Ammonia Test Kit accurately displays changes in the calcium content with accuracy up to 10 mg\/l incrementally.

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.

This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring. The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth. The nitrate concentration in a reef aquarium should be lower than 1 mg\/L, although fish only aquariums would usually have a higher concentration. Just as with nitrite, many nitrate test kits are prone to amine interference which can make the levels of nitrate appear much lower than they actually are. The Salifert test kit does not suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes. The test kit's range goes from a very low to a very high nitrate concentration (approx. 0.2 - 100 mg\/L as total nitrate). Sufficient for 50 tests.
