PhosLess Direct protects against algae by removing the phosphate from the water by physical means and thus reduces algae growth in a natural way. It binds hydrogen sulphide, thereby preventing unpleasant odours. PhosLess Direct offers quick aid in case of excessively high phosphate levels or immediately after algae treatments. The phosphate content is reduced below the 0.035 mg/l limit required for algae to grow. It should ideally be used in early spring to prevent algal blooms during the pond season.
