NYOS Phosi-Ex (500 mL)

Overview

The NYOS Phosi-Ex phosphate adsorber effectively removes excess phosphate (PO₄) from saltwater and freshwater aquariums. Formulated from ultra-pure granules, it provides fast, efficient, and long-lasting phosphate control—helping prevent nuisance algae and promoting vibrant coral coloration and healthy biological balance.
