Product Description

Seachem PhosBond? is a high-performance phosphate and silicate removal media designed for both freshwater and marine aquariums. It uniquely combines aluminum oxide and granular ferric oxide (GFO), delivering faster nutrient reduction than standard phosphate removers while maintaining a high, long-lasting binding capacity.

Its highly porous structure maximizes contact area, allowing rapid adsorption of excess phosphate and silicate?two key contributors to nuisance algae growth. Unlike softer media, PhosBond? is physically durable, meaning it will not crumble, compact, or release bound nutrients back into the water, even in high-flow filtration systems.

PhosBond? is ideal for aquariums struggling with elevated nutrient levels, helping maintain clearer water, improved coral and plant health, and a more stable aquatic environment.

Key Features

• Rapid removal of phosphate and silicate

• Dual-media formulation for faster and longer-lasting performance

• High binding capacity compared to standard phosphate removers

• Durable structure resists breakdown and compaction

• Will not leach phosphate or silicate back into the water

• Safe for use in both freshwater and saltwater aquariums

Directions for Use

• Rinse before use to remove dust

• Place in a high-flow area such as:

  • Canister filters

  • Media reactors

  • Sumps or trickle filters

Recommended Dosage

• 60 mL per 200 L of saltwater

• 60 mL per 400 L of freshwater

Test phosphate and silicate levels after 4 days.

• If levels remain high, replace with fresh media

• If reduced, leave in place until levels begin to rise again

Tip: Continuous use of smaller amounts is more effective than large, intermittent doses.
