RapiClear is designed to clear water gardens and koi ponds quickly and safely by combining suspended particulate together. This process is commonly called “flocculation”. This basically means that suspended organics within the water column attract together, making the accumulated mass heavier than water. This “mass” will eventually drop to the bottom of the pond where a good bacteria colony can utilize the organic mass as food and remove it from the pond, or it will simply get removed by filters, skimmers, etc. RapiClear is made from an all-natural polymer and its primary ingredient is a naturally occurring material in nature. Flocculation should last for several weeks after application. There will be some minor clouding of the water once applied and if pH is high within the water column the product may be neutralized.
