Phos-Zorb should be replaced every 1 to 3 months to ensure continuous removal of phosphate and silicate. The level of these nutrients depends on stocking density, feeding rate, aquarium maintenance schedule and the nutrient levels present in the source water used in the aquarium. Phos-Zorb is often used continually to keep phosphate and silicate levels under control.
