Dosing recommendations

Dose before every use 10-20 grams per m3 (1000L) of spa water

Check the active oxygen content with SpaTime test strips or O2 test Kit as soon as the granules have completely dissolved. It will not be possible to obtain a correct measurement at a later time. The content should be at least 8 mg/L. If this level is not achieved repeat the application by adding the same amount again.

Before each use of the spa, add the oxygen granules directly to spa water, for gentle chlorine-free experience. Always add the product  with the circulation pump running. If the spa is used frequently, you need to double the amount in order to disinfect it sufficiently. The oxygen granules will only reach optimum effectiveness when used along with the active oxygen activator. This product is available as a liquid in 1 litre bottles.


Before adding the disinfectant, please check the pH value with test strips. If required adjust to the correct value of 7.0 – 7.4. this will ensure the best possible efficacy of the oxygen granules.
