Developed by the Australian CSIRO, Phoslock is a highly effective product that removes excess phosphates from any body of water. Safe to use and effective in its application, Phoslock tackles one of the most common and fundamental problems behind unhealthy water.

Why is excess Phosphorus a problem?
Many types of harmful algae feed on Phosphate. Phoslock uses its Phosphorus Locking Technology to remove Phosphorus in ponds, lakes, lagoons and more. If left untreated, high levels of phosphorus in your water can cause devastating algal blooms that may damage the environment and cause serious health hazards to humans and animals alike. If you continuously experience poor water quality, Phoslock might be just the key to tackling the root of the problem. You can now significantly reduce phosphorus levels in your water with this simple product.

Reset the ageing clock
Phoslock offers unrivalled technology in resetting the eutrophication clock (the ageing process) of your body of water, by removing free reactive phosphorus. This product features a unique modified bentonite clay granule build that effectively locks phosphorus into its own particles, which then sink to the bottom. These particles then become part of the natural sediment of the bottom – so there’s no need to remove them after application. Phoslock will continue to absorb phosphorus released from the sediment and new phosphorus inputs until it is saturated.
