Relax Hot Tub pH Plus (soda ash) is a hot tub chemical product that helps balance the pH in the water when your pH levels are too low. The 500g bottle is a handy small container, ideal for the smaller hot tub or small pool

Relax pH Plus for hot tubs and spas corrects the pH when it falls below 7.2. Acidic spa water is uncomfortable to bathe in and if left unchanged, can cause corrosion of metal parts and fittings.

Each dose increases the pH by approx 0.2.With the circulation system running, dose directly in several areas around the spa, avoiding the skimmer. Dose only when bathing has ceased.Continue filtration & re-test after 15 minutes.Repeat treatment until the pH falls within the range 7.2-7.6.
