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

Great value for money. No skin irritation. Use this with a slow release floater for our large outdoor pool mostly (3 tabs per week in a large outdoor pool to keep levels healthy). So the chlorine content is suitable for our pool and we use 1-2 tabs in our hot tub (6 person) so would say chlorine content is slightly higher than you assume. Dissolves slowly. Sometimes after 2-3 weeks when slow dissolving in pool it may not yet be time to replace, but in general fairly stable. Highly recommend. Brought our pool back from the abyss 🤣

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.

Good quality

Good item, fast delivery

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

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

Very good

Always use these tablets they are a great product
