AQUAFORTE PHOSPAT FILTERCARTRIDGE TO REMOVE PHOSPHATES Phosphate is one of the main nutrients for algae (blanket weed) in a pond. With these filter cartridges, it is possible to keep the phosphate level below 0,035 mg/l! This is the "magic" limit that is too low for algae to grow but does not harm plants and bacteria. When the cartridge is saturated it must be replaced (re-filling or regenerating is not possible). A great advantage compared to other phosphate-binding products is that the Phospat does not release the phosphate at all! The phosphate binding capacities of the Phospat cartridges is 30-100 times more compared to Iron (III) oxides. - Reduces phosphate in water and supports the biofilter - Suitable for ponds, natural pools, fountains, and circulation wells - Adsorption capacity is approximately 90.000 mg (Phospat 1) or 270.000 mg (Phospat 3) phosphate - Flow rate up to 1100 l/h (Phospat 1) or 3300 l/h (Phospat 3) - Defined particle size of the individual layers - Suitable for up to ±50m³ (Phospat 1) or 150m³ (Phospat 3) - Several PHOSPATs can be combined for larger volumes of water - The Phospat should be protected against contamination with appropriate pre-filtration - Max. working pressure: Phospat 1: 6 bar, Phospat 3: 4 bar
