AquaForte Phospat Phosphate Filter Cartridges – Phospat 1 & Phospat 3
Professional Phosphate Control for Algae Prevention
 
The AquaForte Phospat range provides high-capacity, non-leaching phosphate removal for ponds, natural pools, fountains, and circulation systems.
By keeping phosphate levels below 0.035 mg/l—the proven threshold at which blanket weed cannot grow—Phospat delivers effective algae control without harming plants or beneficial bacteria.
Unlike many phosphate binders, Phospat does not release phosphate back into the water once captured.
 
Why Control Phosphate?
Phosphate is a primary nutrient driving blanket weed and algae growth. Reducing it to sub-threshold levels stops algae at the source while allowing biofilters and planting to function normally.
 
Key Advantages
Locks phosphate permanently (no re-release)
30–100× higher binding capacity than Iron (III) oxides
Supports biofiltration by reducing nutrient load
Defined particle layers for consistent flow and performance
Modular system – combine multiple units for large volumes
Note: Cartridges are single-use; refilling or regeneration is not possible.
