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.

Key Features

• Powerful phosphate removal: Rapidly binds and reduces PO₄ levels

• High-purity granules: Free from contaminants and safe for reef use

• Long-lasting media: Maintains efficiency over extended contact time

• No clumping or disintegration: Stable granule structure for consistent flow

• Easy to use: Works in media reactors, filter bags, or canister filters

• Reef-safe: Does not leach harmful substances or alter water chemistry
