SuperflockPlus is a further development of Superflock, the best selling product for the removal of cloudiness in pools with sand filters. By using a special cartridge material and a formulation that slows the dissolving process, Superflock Plus has a particularly long-lasting action and removes cloudiness efficiently and for a long time. Plus point: The lanthanum in the new formulation brings about the best possible removal of phosphates, the main nutrient of algae. Thus Superflock Plus also helps prevent algae from growing. Your benefit: The pool water remains crystal clear and hygienically clean. The cartridges are simply placed into the skimmer, where over several days they continually release flocking agent into the water. This achieves a far better effect than just adding conventional flocking agent manually, which only forms flocs for a limited period of time.
