Sapphire Waves5 in 1 Multifunction Chlorine Tablets for Hot Tubs, Spa, Swimming Pools. 1Kg Tub 50 x 20g 1" Spas Paddling Pool Hot Tub Chlorine Tablets for use in Chemicals Floating Dispenser.

I have used these regularly in our hot tub & the work well.

These tablets make keeping a 10 foot pool very low maintenance, literally all I use all summer after an initial dose of granulated chlorine and liquid algaecide. 3 of these in my bobber and my pool is clean and clear for weeks. The lid is a bit dodgy though, difficult to loosen and fasten, sometimes it’s like a super tight child lock then other days it falls off. But the product itself is great.

Good product, good value. Slightly stronger than Chlorine tabs used before so would say use one less than normal or turn down the dial on dispenser a notch

Very good

Brilliant value for money

Good

I bought these for use in a 10ft paddling pool. There are no specific dosage instructions and I didn't have a floating dispenser so just threw them into the pool. They kept the water clean looking but bleached the colour out of the base of the pool. I would use with caution! They were in the pool approx 24hours and barely changed in size.

Does what it's meant to
