Spa Store pH Decreaser 500g

Reduces the pH level in spa and pool water for more effective chlorine performance and superior water comfort.

It is natural for your spa water pH to move above the desired levels which makes spa water uncomfortable and it also reduces the effectiveness of chlorine sanitisers which costs you money.
