The Shark PRO Zerophos Cartridge is an all-in-one replacement media pack designed for the Sicce Shark PRO series of internal aquarium filters. This convenient cartridge provides powerful two-stage filtration to improve water quality and clarity in both saltwater and freshwater aquariums. Its primary function is to chemically remove phosphates and silicates, which are common fuel sources for nuisance algae, helping you maintain a cleaner and healthier aquatic environment.

This replacement kit includes one cartridge pre-filled with high-efficiency Zeophos chemical filtration media, alongside two 20 ppi mechanical filter sponges. The sponges effectively trap detritus and free-floating particles, while the Zeophos media adsorbs unwanted dissolved compounds. The cartridge is fully compatible with the Sicce Shark PRO 500, Shark PRO 700, and Shark PRO 900 internal filter models, ensuring a perfect fit and seamless operation.

This product is ideal for any aquarist using a compatible Sicce Shark PRO filter who wants a simple and effective solution for controlling algae and maintaining pristine water conditions. By combining mechanical and chemical filtration into a single, easy-to-install unit, it simplifies filter maintenance significantly. It is an excellent choice for hobbyists looking to proactively manage nutrient levels and reduce the workload associated with keeping their display tank looking its best.
