ClearwaterCH0019 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

These are great for keeping my pool ph and chlorine balanced. They are easy to use with a dispenser and only have to top up every week or two. The dissolve over time and my 3m x 2m pool never needed any additional chemicals to balance. Good quality product with the added bonus of including algaecide to stop the green algae appearing. Much easier than using seperate chemicals and good value for money.

I am incredibly impressed with the quality of this product. The simple convenience of using these to keep on top of the chlorine levels in my hot tub is enough to ensure that I will purchase them again.No measuring is required, but would definitely recommend using a tablet dispenser specific to your hot tub or pool as it allows slow release of the chlorine.It does take 3-5 days for the chlorine to dissolve, so wouldn’t recommend using these for the initial dose as the water tends to benefit from a shock treatment (which these tablets won’t necessarily offer). For ongoing management and maintenance of chlorine, they definitely do the trick!

I brought these to treat a 12ft above ground pool. It's been 3wks now and so far they are working a treat. I'm using them in a floating holder, when I test the chemical levels all 4 are ok with only 1 slightly high the free chlorine. The water has remained clear and no swimming bugs. It has a slight chlorine smell so all good. The pool has a filter pump which goes on every other day and a cover which rests on the water to help warm the water using the sun. All good thank you.

I Have used it over a number of years and it helps

Bought these as I was feed up with mixing the liquids. Popped these in the floater I already had. Perfectly clear water. So much easier as well I put in two to start off with but put in 4 and got the correct levels. Take a while to dissolve. I’ve had to bag the tub as the cupboard they were in smelt very strong of chlorine. Great value for money

The real thing ! As there can be dupes on here , amazing price as I was paying £20 for 1kg and there is 5kg in here . So easy to use no faffing with powders or ph ups n down it’s pretty spot on every day ready to go . My water has stayed clear , no slime and only need to use one tab approx every 3 days .

These tablets/pellets are great for keeping your hot tub water nice & clean & stops any algae from forming, they last a while before they need to be replaced dissolving slowly.There are cheaper brands out there but I find these ones are superior.

So much easier to use than granules. Pop 1 in the floater and that's it. All levels seem spot on and I don't get the slimy film at the bottom or side when using these. Will definitely use them again when they run out.
