Aquaforte Phospat 3

Aquaforte Phospat 3

Phosphate removal through a replaceable filter cartridge

AquaForte Phospat 3 is the larger phosphate-removing cartridge in the Phospat range. It is designed for ponds, swimming ponds, fountains and circulation wells where phosphate reduction is needed to reduce one of the main food sources for blanketweed and algae.

Aquaforte Phospat 3 is an advanced, high-capacity phosphate remover designed to dramatically reduce the phosphate levels in your pond water—the primary nutrient responsible for blanketweed and algae growth. By keeping phosphate levels below the critical threshold of 0.035 mg/l, the Phospat 3 makes it nearly impossible for algae to thrive, without harming aquatic plants or beneficial bacteria. With an adsorption capacity of up to 270,000 mg, Phospat 3 outperforms traditional phosphate removers such as iron (III) oxide by up to 100 times.

Unlike many competing products, the Phospat permanently locks in the phosphate, preventing any release back into the water, even when saturated. Ideal for use in ponds, natural swimming pools, water features, and recirculation systems, this unit handles a flow rate of up to 3300 litres per hour and is suitable for water volumes up to 150,000 litres (150m³).

Water testing products are the starting point for most pond treatment decisions. Accurate test results help show whether the issue is ammonia, nitrite, pH, KH, phosphate, chlorine, nitrate or another water parameter. This avoids guessing, reduces unnecessary dosing and gives a clearer record of how the pond responds after treatment, water changes or filter maintenance.

AquaForte water treatment products include phosphate control, water improvement and sludge/nutrient management. Their Phospat products reduce phosphate, one of the key nutrients that feeds filamentous algae and green water issues.

Using the phosphate cartridge

Fit the Phospat cartridge behind a suitable pre-filter so dirt does not block its media. Test phosphate before and after use, maintain the specified flow and replace the cartridge when saturated.

Key benefits

• Uses solid media to bind phosphate from flowing water
• Removes dissolved phosphate through a replaceable media cartridge
• Useful for koi ponds, garden ponds and larger pond systems
• Works alongside water testing; it is not a measurement device
• Works alongside separate phosphate tests to check performance
• Use a pre-filter and replace the cartridge when exhausted
