From a chemical standpoint, hot tub shock is an oxidizer. An oxidizer is a chemical that causes impurities to lose electrons, and that causes them to break down quickly. These are in powdered or liquid form and can come in various chemical composition: chlorine in granular form, non-chlorine salts, or liquid chlorine.
People also ask, can I add shock and chlorine at the same time?
Adding chlorine besides the shock can increase the chlorine content in the water which can make the entire shocking process useless. Hence, it is better if you don’t use the shock and chlorine at the same time. The best time to add chlorine to the pool water is after you have shocked the pool.
Beside this, can you add too much non-chlorine shock?
If too much is added, it can cause the overall pH level of the pool to drop for a sustained period, which you’ll then have to raise. … Finally, using a non-chlorine shock treatment will lower the pool’s total alkalinity, and at the same time, raise the TDS (total dissolved solids) level in the water.

How much shock do I need for a 300 gallon hot tub?
For a 300 gallon spa, 0.7 oz of Chlorine Granules shaken over the water surface, will raise the chlorine level up to about 10 ppm. This should be done with a balanced pH (in the low range of 7.2-7.4), and with the circulation pump running on high to help distribute the shock quickly.
Is spa oxidizer the same as shock?
Shock Treatment (Oxidizer):
Dichlor – A form of chlorine used as both a sanitizer and a shock, typically used only when you refill your hot tub.
Is spa shock the same as chlorine?
