"CleverSpa Universal Stabilized Hot Tub Chlorine Granule Pool and Spa Rapidly Dissolving Chemicals for Safe and Sanitizing of your inflatable hot tub water, 1KG"

Performance great. Well priced. Easy to use.Fast delivery. And very well packed

After doing plenty of research, these are the best value chlorine granules I could fine online for my lazy-spa hot tub. The price was simply unbeatable.The actual granules are exactly the same as the more expensive 'clever spa' ones so save yourself a bit of money and time with these.I have the lay-z spa Helsinki and calculated that roughly one heaped cap (the screw cap from the tub) is enough chlorine for my hot tub for a few days.There are also useful measurements on the back if you want to be super accurate with the amount needed per volume of water and further instructions on how to dissolve the granules and how to test your spa.Delivery was also super quick only taking 2 days to come! Highly recommended product and definite buy for any hot tub owner.

Recommended for good size bottle 1ltr for price (I normally buy 500ml for more) and now my pool and garden has a lovely chlorine smell so seems to do the job.

Brilliant stuff. Sorted hot tub in no time. Thank you 😊

Works as it should

used for killing algae in drain pipes from washing machine.

Found this just as effective as some of the more expensive options!!

This product is perfect for our hot tub but came in a HUGE box with tons of plastic. This has put me off buying in the future
