PO4 PRO
Phosphates (PO43–) are important nutrients for all plants and are irreplaceable for the energy metabolism of every living cell. Phosphates enter the aquarium water through food and the decomposition processes of organic matter. However, an uncontrolled increase in phosphate content causes problems, such as strong algae growth. In marine aquariums, phosphates can also severely hinder the separation of calcium carbonate for the composition of the calcareous skeleton of scleractinians, thus severely hindering their growth. On the other hand, in the case of large plant and/or coral populations and a small fish population, phosphates can also become a deficient element that must be replenished. In some reef aquariums, extremely nutrient-poor conditions are specifically created – in such cases, phosphate deficiency can sometimes occur.
For freshwater, a phosphate value of up to 0.4 mg/l is adequate, but it should not exceed 1 mg/l. A concentration of 0.02 mg/l is already sufficient for the nutrient supply of aquatic plants. In natural seawater, the phosphate content is approximately 0.06 mg/l. However, in coral reefs this value is much lower; there, concentrations between 0.01 and 0.02 mg/l are found.
In general, it is recommended not to allow the concentration to rise above 0.1 mg/l in seawater tanks, and in reef aquariums in particular to keep it between 0.01 and 0.05 mg/l. In any case, the phosphate concentration of the aquarium water should be checked regularly.
