API Phos-Zorb is a ready-to-use filter media pouch that removes phosphate and silicate from freshwater and saltwater aquariums. These common nutrients build up from fish food, waste and tap water. They can contribute to cloudy water and algae growth, including brown diatom algae fuelled by silicate.

Just place the pouch in your filter and it gets to work as water flows through. By keeping phosphate and silicate low, Phos-Zorb helps keep your water clearer and can reduce aquarium maintenance. The pouch format suits most filters.

Key Features

• Removes Phosphate: Helps reduce a key nutrient behind algae growth
• Removes Silicate: Helps control brown diatom algae
• Clearer Water: Helps reduce cloudiness and debris
• Less Maintenance: Helps keep glass and décor cleaner for longer
• Ready to Use: Pre-filled pouch for easy placement
• Fresh and Saltwater: Suitable for both aquarium types

How to Use

1. Rinse the pouch in old aquarium water to remove any dust.
2. Place it in your filter where water flows through it, ideally after mechanical filtration such as sponges or floss.
3. Test phosphate regularly, and replace the pouch when levels start to rise again.

Please note: Phosphate is a nutrient that live plants need. In heavily planted tanks, use with care and monitor plant health. Phos-Zorb supports good water quality but doesn’t replace regular water changes and filter maintenance. Keep out of reach of children.

Suitable For: Freshwater and marine aquariums with algae or cloudiness linked to phosphate or silicate, including reef tanks.
