Pool Stabiliser 1.5kg Bluewater

 Bluewater Pool Stabiliser contains cyanuric acid.  Useful to protect your chlorine from breakdown in UV light so your chlorine lasts longer.

Bluewater Pool Stabiliser should be placed in a stocking and hung in the pool to slowly dissolve. Usually only required to add at the start of the swimming season (depending on which type of chlorine you use).
