CosySpa PH Plus – Ideal For Hot Tubs & Swimming Pools

Ensure your hot tub/swimming pool water remains perfectly balanced with the CosySpa PH Plus. The natural pH enhancer is the ideal treatment for pools & spa water. The product can be used to increase the pH balance of the Spa/Hot Tub water. The correct pH balance is critical to ensure bather comfort and to minimise damage to the fabric of the SPA/Hot Tub. The correct pH balance for the water is between a reading of 7.4 and 7.6. The 1.5kg tub will help stabilise the water without the use of toxic chemicals – therefore enhancing the longevity of your pool/system too.
