Dolphin Shock Support

Spa Shock Support is used in combination with Spa Shock or Spa Brom Tabs 20g. As a result, Shock Support acts as an activator and significantly increases the disinfection effect. Spa Shock Support can also be used together with chlorine products.


Check first! Before adding the algaecide, measure and check that the pH and disinfection values (chlorine, bromine, active oxygen) are at a good level.

Shock Support

Then add 30 ml of Shock Support per 1000 litres when refilling the water. Slowly pour the algaecide into the water along the edge of the spa.
As a maintenance dose, add the same amount once a week.

Ph Value is important

The pH value is measured with a pool tester/test strips. At pH 7.0-7.4, the water feels nice and comfortable when bathing. If the pH is below 6.9, add pH up. Carefully sprinkle the amount of granules to be added to the bath water while the massage pump is on.
After about 3 minutes, take another measurement of the pH value.
Repeat the treatment if necessary by adding another dose of pH Up until the pH is between 7.0 and 7.4.
If the pH is above 7.4, use pH minus with the same method as described above.

Recommended values

Always! You should therefore pay close attention to the dosage and also check and adjust the bromine, pH and alkali levels regularly to the recommended values:
Bromine 2,0-4,0 mg/l;
pH 7.0-7.4;
Alkalinity 80-120 mg/l.


You change the bathing water regularly and at the same time you clean the spa. You should use Delphin Spa Pipe Cleaner to clean the built-in pipe system. You do this 3-4 times a year. After cleaning, you take the opportunity to change the filters or clean them thoroughly. After this work, it is time to fill up with new bath water that you shock treat with Oxi Booster or Spa Shock.
