Product description

SpaBoss Spa Shock is a non chlorinating shock treatment for Hot Tubs. Spa Shock works quickly in oxidizing many kinds of contaminants that reduce the effectiveness of your hot tub's chlorine or bromine. When used regularly, Spa Shock helps to reduce chlorine or bromine demand by removing those unfilterables. Spa Shock will not affect the water's pH level. Spa Shock will help restore water quality and give a boost to the chlorine or bromine levels.

Important information

Directions

1. Add 99.2g (about 3.5 caps) of Spa Shock per 1000 gallons of water weekly. 2. Use Spa Shock as a non-chlorine shock treatment for spas. 3. Oxidize various contaminants that reduce chlorine or bromine effectiveness. 4. Help reduce chlorine or brome demand by eliminating contaminants. 5. Spa Shock does not affect pH levels. 6. Restore water quality and boost chlorine or brome levels.

Must have been defective.
This is my pool water 24hrs after adding the entire 3kg. No change at all. I thought something was weird when it didn't smell like pool shock.

    4.0 out of 5 stars Needs a measuring scoop.
    Reviewed in Canada on March 1, 2025
    Verified Purchase
    The manufacturer needs to provide a better way to determine how much to add to a spa. I can do the calculation to figure out how many grams per my volume of water, but I need a way to measure out the grams. I bought the pail container of shock and there is no scoop. Some guidance like how many grams are in a tablespoon for example would be helpful.

    I just got a hot tub in September (it's December now), and I had a tough time figuring out the chemicals at first, but then I figured out how to balance things and keep the water at the right levels. This product is great, I add a couple scoops every couple days and it keeps the bacteria down and keeps the water where it should be. Good product!
