How To Shock Dose Your Lay-Z-Spa Hot Tub
Shock dosing your Lay-Z-Spa water refers to adding larger quantities of hot tub chemicals to your water in order to break down any organic waste and contamination and re-establish a positive level of water cleanliness. A shock dose is often performed using chlorine granules, with chlorine tablets being used to maintain the correct daily chlorine level.
When Do I Need To Shock My Spa Water?
Your Lay-Z-Spa water should be shocked when:
- You first fill up your Lay-Z-Spa
- At the first signs of algae or slime
- After periods of heavy usage
- After a loss of water clarity or quality
How Often Should I Shock My Spa Water?
It is good practise to shock treat the spa water with ClearWater Chlorine Granules after a period of high usage. This will help to rectify the sanitizer level, prevent the growth of microorganisms and help maintain sparkling, crystal clear water. After treatment, water quality and clarity is often completely restored.

Shocking your hot tub is essential for hot tub maintenance by helping to prevent the build of bacteria.

Experts recommend shocking your hot tub before first use and then at least once a week - initial setup only, should be maintaining levels daily so not required to keep your water clean and clear.
To shock dose, follow these six steps:
1 Ensure that your spa is filled with water up to the recommended level.

3 There are two types of shock dose:
Commissioning Chlorine Shock Dose: This is the shock dose you add to your spa when you first add water to it
Normal Chlorine Shock Dose: This is the shock dose you add to your spa when it has already previously had a Commissioning Chlorine Shock Dose.
4 Check the water capacity of your hot tub. The size of your hot tub will impact just how much chlorine you need to add to your spa. Use the Shock Dose Recommendations Table below to see how much Chlorine you need.
