Although phosphates are necessary for plant growth, only in very small concentrations they are not harmful. ABA PHOSPHAT ZERO quickly eliminates phosphates and silicates. Reduces algae growth. It should be inserted into the filter or sump, with the supplied bag, without rinsing. Its duration depends on the concentration of phosphates. In marine water the presence of phosphates should be kept below 0.015 mg/l. A PO4 test is recommended to determine when to change ABA PHOSPHAT ZERO. Approximately once every 2 months. When setting up a new aquarium, use ABA PHOSPHATE ZERO immediately to ensure that a high concentration of PO4 does not develop. A slight red cloudiness of the water shouldn't worry as it is not harmful to plants and animals and is short-lived.
