Phoslock

Phoslock is an environmentally-friendly tool in algae management. It was developed in Australia by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Phoslock is a natural product which starves algae of phosphate, thereby preventing its growth. Unlike many other treatments for blue-green algae, no chemicals are used. It works by locking away the phosphate present in the water body, permanently preventing its re-release for use by algae. It is a simple solution which has fast, effective and proven results. One Kilogram of Phoslock treats 12,000 Litres of water; mixed with water to form a slurry and distributed around any pond or water feature.
