PhosLess Direct removes the algae nutrient, phosphate, from pond water quickly and effectively. The phosphate content can therefore be reduced under the limit of 0. 035mg l, which is required for algae growth. You can therefore sustainably protect your pond from excessive algae growth. Dosage: Evenly distribute approx. 50ml for every 1000 litres over the surface of the pond
