All our natural clarifiers are totally biodegradable and safe to use. Prepared using the natural ingredient chitosan and made using environmentally sound and sustainable methods, Pennosan’s Natural Pool Clarifier will help to keep your swimming pool or hydrotherapy pool clean and crystal clear.

Chitosan is a natural flocculating agent that will gather up any dirt present in your pool water. When used in conjunction with sand or glass filter media, our Natural Pool Clarifier will clear the pool of dirt, grime, and clarify any milkiness. Our Natural Pool Clarifier will collect any dissolved metals, oils and cosmetics present in the water, preventing staining, making them easy to remove with conventional filtration systems. As well as being an excellent clarifier, chitosan is naturally anti-microbial, reducing demand on sanitisers.

Using this product on a regular basis will keep swimming pool water clean and clear and will also enhance the performance of sanitising products by reducing total dissolved solids (TDS).

Backwashing the filter removes this product together with any trapped dirt and oils. Once used our Natural Pool Clarifier will dissolve away naturally, safely and free of chemical residues. Filter washings can be flushed to ground with no risk of harm to your garden or to the environment.
