One of the primary nutrients for algae (also known as blanket weed) in ponds is phosphate. It is feasible to keep the phosphate level below 0,035 mg/l with these filter cartridges! This is the "magic" limit that prevents algae from growing while yet being safe for bacteria and plants. The cartridge needs to be replaced when it becomes saturated (re-filling or regenerating is not possible). The Phospat does not release any phosphate, which is a huge benefit over other phosphate binding products! When compared to Iron (III) oxides, Phospat cartridges have 30-100 times greater phosphate binding capacity.
- Lowers the amount of phosphate in water and helps the biofilter.
- Appropriate for fountains, circulation wells, natural pools, and ponds.
- The amount of phosphate that can be absorbed is approximately 90.000 mg (Phospat 1) or 270.000 mg (Phospat 3).
- Up to 1100 l/h (Phospat 1) or 3300 l/h flow rate (Phospat 3)
- Specified particle size for each layer.
- Capable of accommodating up to 50m3 (Phospat 1) or 150m3 (Phospat 3)
- Multiple PHOSPATs can be used to treat larger amounts of water.
- Appropriate pre-filtration should shield the Phospat from contamination.
- Phospat 1: 6 bar, Phospat 3: 4 ba, maximum working pressure
