The API Phos Zorb is a specialized filtration media designed to effectively remove phosphate and silicate from aquarium water, preventing unwanted algae growth and promoting a clean, healthy aquatic environment. Suitable for both freshwater and saltwater aquariums, this product helps improve water clarity and maintains stable water chemistry for fish and plants.
Removes Phosphate & Silicate: Effectively eliminates excess nutrients that contribute to algae growth.
Improves Water Clarity: Keeps aquarium water clear and free from haze caused by dissolved organics.
Safe for All Aquariums: Ideal for use in both freshwater and marine setups.

Rinse the Phos Zorb pouch under clean water to remove dust before placing it in your filter.
Position it in an area of high water flow within the filtration system.
Replace the pouch every 2 months, or sooner if phosphate or silicate levels begin to rise.
Test water regularly to monitor phosphate and silicate concentrations.
Use API Phos Zorb as part of your regular aquarium maintenance routine to maintain low nutrient levels and prevent algae outbreaks. For best results, pair it with API Bio-Chem Zorb or API Nitra-Zorb to achieve comprehensive water purification and long-term aquarium stability.
