JOVS Non Chlorine Shock 5kg - Spa Treatment for Hot Tubs & Swimming Pools - Water Clarifier, Paddling Reducer, Cleaner, and Pool Maintenance Essential - Included Pool Chemicals.

Although I have only used this a few time now I can tell already that this is a much better quality product than the last 1 litre tub that I bought. The spa seems to clear a lot quicker now after use as goes back to crystal clear water within a day which the other product seemed to struggle with. Obviously buying as a 5 litre tub is much better value for money in the long run and using this for my hot tub should last well over a year going with the quantities on the instructions. It's very easy to use, just mix the required amount in some water and add it to the tub with the jets on. The only thing is the instructions are for swimming pool quantities but nothing that a little maths didn't solve. Basically for around a 1000 litre tub 12g to start and 6g as a maintenance. I will buy this again.

⭐️⭐️⭐️⭐️⭐️ 5-Star Review: Outstanding Value and Performance We've been using the JOVS Non-Chlorine Shock (5kg) in our professional flotation room and couldn't be more impressed. Compared to other, more expensive brands we've tried over the years, this one holds its own - and then some. Not only is it long-lasting and highly effective at maintaining water clarity and hygiene, but it also performs consistently well in a high-use environment. Clients always comment on how fresh and clean the float experience feels, and we're confident this product plays a key role in that. What really sets it apart is the excellent price point. You're getting reliable, high-quality results without the inflated cost – a rare find in the wellness industry! Highly recommend for anyone running a float centre, spa, or even just looking for a trustworthy, non-chlorine shock for home use. This will definitely be our go-to from now on.

Non chlorine shock treatment, works well for my hot tub.

Excellent product does exactly what it says on the tin. Keep my swimspa crystal clear

Item arrived on time and as described.

Great

Cleared the water in my very murky tub

Seems expensive for what it is but 5kg at least lasts a while. Seems to work well and keeps my hot tub from going green.
