Calcium is a chemical element with the element symbol CaCalcium is extremely important for most reef inhabitants, but especially for stony corals and lime red algae. Reef-building hard corals (SPS) require some calcium in high amounts for the skeletal structure. LPS hard corals have somewhat lower calcium content requirements.In seawater aquaristic..
Iron FE is a chemical element with the element symbol (Fe).Iron is a vital trace element for almost all living beings, in animals especially for blood formation. Nevertheless, the iron content in marine aquarium should be within certain limits. If, for example, excessive algae growth occurs despite a low supply of nutrients, then the cause may be a..
Iodine is a chemical element with the symbol (I)Iodine (or iodine) is extremely important for most reef inhabitants, especially invertebrates need it to maintain cell functions. The iodine concentration in the oceans is between 0.025 - 0.064 mg / l.Many colors of coral in the marine aquarium are enhanced by iodine - especially in combination with p..
Potassium is a chemical element with the element symbol KPotassium is also called potassium in many languages because it could also be obtained from potash when it was discovered. Potassium is one of the most abundant elements found in many minerals in the world.Potassium should always be present in sufficient quantities in marine aquariums..
The carbon hardness value ( KH ) indicates the alkalinity - ie the hardness (in ° DH) of the water. The alkalinity depends on the amount of basic ions present in the water, mainly the content of carbonates.Carbonates serve to supply corals with carbon. The carbon (carbon) contained in the bicarbonates is important for the photosynthesis of corals.T..
Magnesium is a chemical element with the element symbol MgMagnesium is extremely important for most reef inhabitants, but especially for corals. Magnesium together with calcium is responsible for the alkalinity (KH), ie the hardness in the water. Magnesium is consumed in seawater aquarium in significantly lower amounts than eg calcium, but should s..
Ammonium ( NH 3 ) and ammonia ( NH3 ) are chemical compoundsAmmonium (NH3) is converted into very toxic ammonia (NH3) by high pH values and higher temperatures (such as those found in saltwater aquariums). Ammonia is a chemical compound of nitrogen and hydrogen and is produced by the decomposition of dead plants, dead animals and animal excrement..
Nitrite NO2 is a chemical nitrogen compound and contains nitrogen as an essential ingredient. The majority of nitrite in the aquarium is converted to nitrate (NO3) by nitrification. Nitrification is the bacterial oxidation of ammonium (NH4) / ammonia (NH3) to nitrite (NO2) and then to nitrate (NO3).Particularly in newly established marine aquariums..
Nitrate ( NO3 ) is a chemical nitrogen compound and contains as its essential ingredient nitrogen, which is of particular importance as a nutrient for corals. However, excessive nitrogen concentrations lead to overfertilisation and thus to increased algae growth.Nitrogen, however, is needed by all living things for growth, so the right concentratio..
The pH value indicates the acidity (alkalinity) of the water.The pH value is a measure of the acidic or basic character of an aqueous solution. The measurement of the pH value is one of the most important measurements in the aquarium. It is extremely important to compare the pH value with other measurements on other days at the same time of th..
Phosphate ( PO4 ) is a chemical compound and contains the element phosphorus.Too high phosphate levels in the marine aquarium lead to over-fertilization of the zooxanthellae living in symbiosis with the corals and lead to a brown coloration of the corals. In addition to the presence of dissolved phosphate in the water, this can also accumulate in s..
