Non-Chlorine Shock

This stuff is amazing...struggled with the summer heat to keep the hot tub looking non cloudy....there's only so much alkinity and chlorine granules you can use but put this in and keep changing the filter...it works a treat...now the maintenance is stress free and surprised how quickly it makes the water clear

Good value for the money works well

Needed Shock for my Hot Tub. Seemed like the best of a bad bunch when i was searching. Seems to do the job

I have been using chlorine in our 900litres hot tub but decided to try Bromine on recommendation to avoid chlorine after a refill and cleaning. Never used a shock treatment as testing chlorine levels, pH etc have been fine and water clear and sparkly. After 7 days Water + Bromine became cloudy and eventually yellowy with a slimy feel to the tub walls and floor. Bromine not registering on test strips. (Thought about draining and refilling using chlorine), Added 1 shock treatment recommended dose day one - nothing. Added shock treatment 2 three days later - bromine registering activated and water less yellow Added shock treatment 3 two days after 2nd dose - bromine, pH and alkalinity all good and water looking clearer, clean and no sliminess.

This has been ideal for our hot tub. It is a lot cheaper than the usual shock treatment that we purchase, easy to use and since we started using it, it has kept the water stable. Overall, its very effective and I will buy again.

Ideal item for shocking your tub.

Quick delivery only just used it so hopefully as good as reviews. Just let down it's half full. I would have returned it but it was needed.

I was disappointed after a single use - but following online advice I now apply the shock about weekly (we use the hot tub every day and at least 2 of us). The water clarity has improved significantly. It is easy to use, but does have to be left a while with the lid up and the pump running before getting in again.
