Stabilised Chlorine Granules for Hot Tubs and Swimming Pools - 1kg by RockWaterAir

We use this for our Lay-z-spa Miami when it needs the water changing (use tablets in a floater the rest of the time). The previous 500g tub lasted for years, so I shouldn't need any more for many years to come!Works well and has a handy dosing guide on the outside of the packaging. Quite a bit cheaper than the big brands and exactly the same stuff.

I usually buy my tubs of chlorine from an independent hot tub store where I live but I decided to try these as they were cheaper for a bigger tub. I’m not disappointed. Water is crystal clear and smells nice and fresh. Will be buying more.

It's chlorine. It does what it says.
