BIOSTAR® Liqui-Floc® P
It effortlessly lowers the phosphate content to below the required value of 0.035 mg/l PO4, thus reliably and ecologically preventing mass algae growth. To achieve the best possible results, we recommend adjusting the pH value of your pond to 6.8 - 7.6. 1 liter of BIOSTAR® Liqui-Floc® P can remove ~ 80 g PO4.
