API Phos Zorb filtration media

API Phos-Zorb Aquarium Filtration Media – Phosphate & Silicate Remover for Clear Water

Phosphate finds its way into an aquarium through fish waste, decaying organic matter and even tap water, and once levels build up, cloudy or discoloured water often follows. API Phos-Zorb is a phosphate-removing filter media in a specialised pouch, designed to clear water affected by phosphate and silicate build-up.

In saltwater and reef aquariums, Phos-Zorb helps hard and soft corals thrive by keeping these nutrients in check, while in freshwater tanks it removes compounds that can otherwise hold back healthy plant growth. Simply place the pouch in the filter’s water flow and let it get to work.

Features & Benefits

• Removes phosphate and silicate to clear cloudy water
• Supports healthy coral growth in saltwater and reef aquariums
• Removes compounds that inhibit plant growth in freshwater tanks
• Convenient pouch format, simply rinse and place in the filter’s water flow
• Rinse under tap water for several minutes before use to remove dust and activate the media (this may generate some heat, which is normal)
• Replace every 2 months, or sooner if testing shows phosphate or silicate present

Recommended For

• Saltwater and reef aquariums, to support coral health
• Freshwater planted aquariums affected by phosphate or silicate build-up
• Use when testing shows phosphate above 0 ppm/mg/L or silicate above 0.5 ppm/mg/L
• Aquariums experiencing cloudy or discoloured water
