Phosphate, a major nutrient for pond algae (blanket weed), can be effectively controlled using these filter cartridges, maintaining phosphate levels below 0.035 mg/l. This level is ideal, as it prevents algae growth in your Swimming Pond while not affecting plants and bacteria. Once saturated, the cartridge should be replaced, as refilling or regeneration is not possible. An advantage over other phosphate-binding products is that Phospat does not release phosphate. It offers an impressive binding capacity, 30-100 times higher than Iron (III) oxides.

Key Features:

• Reduces phosphate and supports biofilters.
• Suitable for Swimming Ponds, fountains, and circulation wells.
• High adsorption capacity: around 90,000 mg (Phospat 1) or 270,000 mg (Phospat 3) of phosphate.
• Flow rate up to 1100 l/h (Phospat 1) or 3300 l/h (Phospat 3).
• Precise particle size of individual layers.
• Suitable for volumes up to ±50m³ (Phospat 1) or 150m³ (Phospat 3).
• Multiple PHOSPAT cartridges can be combined for larger water volumes.
• Protect Phospat from contamination with suitable pre-filtration.
• Max. working pressure: Phospat 1: 6 bar, Phospat 3: 4 bar.
