Clearwater 1 kg Multifunction Chlorine Tablets, 4-in-1 Dispenser Tablets (Sanitiser, Stabiliser, Algaecide and Clarifier) for Pools and Hot Tubs, 50 x 20 g, White

Wouldn't buy a different product! These are super easy to use and work very well. Last a long time. Never had an issue. Keep hot tub clean and smelling fresh. Would recommend.

I buy these regularly. totoally fine.

bought a tub of these last year for the hot tub and they work brilliantly, the first year i used the tub i used to dissolve chlorine crystals in warm water then pour it into the tub and then check before usage that the level was right.. what a waste of time !!!! with these i just make sure there is always one in the self soaking dispenser clipped on the inside where the water is pumped back into the pool all the time and only randomly check the levels as know if there is a chlorine tablet then the water has chlorine. they work out slightly dearer then buying a big tub of crystals but to save all that faffing about is worth it. never had any irritations on the skin or eyes as just enough chlorine in each tablet, well worth every penny. and importantly the branded make I go for

Good item, fast delivery

Easiest way to look after your hot tub spa water quality. Always works well , and if you need a boost just add 2 to your dispenser. Fast delivery , good price …does the job

Easy to use, just put one in a float for the tub and saves the hassle of adding different chems into tub

These keep my hot tub nice and clear over summer. No unpleasant smell and handy container

It is what it says it is in the advert. Appears to do the job.
