Recommended Parameter Levels for Spas

Bromine in Spas-Recommended bromine levels in the UK for pools and spas are 4.0 – 6.0 mg/L with shock dose of 10 mg/L.

Calcium Hardness in Spas – Calcium hardness should be measured once a week, and a level between 80 – 200 mg/L maintained.

Chlorine (Free and Total) in Spas – If chlorine is being used in a well-designed spa you should be looking for a free chlorine residual of 3.0 – 5.0 mg/L. The combined chlorine should be as low as possible and certainly less than half the free and never more than 1 mg/L.

Cyanuric Acid in Spas – Levels should be below 200 mg/L, with many authorities suggesting levels between 25 and 50 mg/L are ideal.

pH in Spas – Ideally you are looking for a pH of 7.2 – 7.4, an overall range of 7.0 – 7.6 is acceptable in most spas.

Phosphate in Spas – The level of total phosphates in the spa water should be 0.01 mg/L or below.

Total Alkalinity in Spas – Levels should be in the range 80 – 200 mg/L CaCO3.

Turbidity in Spas – The level of turbidity should be 0.5 NTU (Nephelometric Turbidity Units) or less.
