Spa Fresh Ultra pH Down 500g

Product Description 

Spa Fresh Ultra pH Down 500g is a water balancing treatment specifically formulated to lower pH and total alkalinity levels in spa and hot tub water. Maintaining the correct pH range is essential for bather comfort, equipment protection and effective sanitiser performance. 

When pH and alkalinity levels become too high, spa water can become scaling, causing calcium deposits, cloudy water, inefficient sanitiser performance and potential damage to heaters, pumps and pipework. Spa Fresh Ultra pH Down effectively reduces pH and alkalinity to help restore optimal water balance.  

Regular testing and adjustment of water chemistry helps maximise sanitiser efficiency, improve water clarity and extend the lifespan of spa equipment.
