API SuperClean Phos-Zorb Cartridges

Designed specifically for use with the API SuperClean 5-20 Power Filter, Phos-Zorb Cartridges effectively eliminate cloudy water caused by the presence of phosphate and silicate. They also help to reduce the overall maintenance requirements of your aquarium. Phos-Zorb is scientifically proven to remove phosphate and silicate, nutrients commonly found in freshwater and saltwater aquariums. It also promotes the growth of reef-building corals and prevents calcium precipitation caused by excess phosphate. Safe for all fish, invertebrates, and plants. Also provides effective mechanical filtration by removing fine debris. Phos-Zorb Cartridges are not only filled with superior media, but they are also densely filled to provide even more filtration capacity. Use when testing indicates the presence of phosphate or silicate (greater than 0 ppm). Ideal for freshwater, saltwater, and reef applications.
