Phosphate is one of the main nutrients for algae (blanket weed) in a pond. This filter cartridge makes it 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.
? Reduces the phosphate in the water and supports the biofilter.
? Suitable for ponds, swimming ponds and fountains.
? Can absorb up to 90,000 mg (Phospat 1) or 270,000 mg (Phospat 3) phosphate.
? Consists of three layers of filter media.
? Multiple Phospat cartridges can be combined for larger ponds.
? Phospat cartridges should at least be placed behind a pre-filter to prevent contamination.
