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.

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

Good item, fast delivery

This is a great price for chlorine tablets. I have a lay-z-spa and I put two in my dispenser and they last roughly a week, which is longer than the cheaper versions. I have purchased cheaper tablets however ended up using more in less time. Definitely worth the money and keeps my spa lovely and clear!!

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

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

Good value
