Salifert KH/Alkalinity Profi-Test
Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow. Carbonate and bicarbonate are also needed and these two substances can ...
Salifert Magnesium Profi-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 photosynth...
Salifert Nitrite Profi-Test
In a properly cycled aquarium, nitrite is converted to nitrate and then, if there are areas deprived of oxygen such as in live rock and other filter materials, this nitrate is converted back to ...
When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium wher...
Salifert Oxygen Profi-Test
Corals and marine fish require very high levels of oxygen concentration because of the low solubility of oxygen in salt water so it is very important to regularly test the level of oxygen present...
Ammonia and ammonium should be rapidly converted by aerobic nitrification into nitrite and then nitrate and finally into nitrogen gas. If this does not happen then either the aquarium is not fully matured or there is a problem...
Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.
Salifert Silicate Profi-Test
Silicate occurs in tap water or purified water when the reverse osmosis or de ionizing unit is not functioning properly.
Silicate can result in diatom bloom and can block some essential trac...
Salifert Copper Profi-Test
Copper is often used as a treatment for parasite infested fish and it is essential that the correct concentration is used as too high levels can be toxic to marine fish and invertebrates.
Salifert Phosphate Profi-Test
If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth rate of corals and ca...
