4in1 Multifunction Chlorine Tablets for Hot Tubs, Spa, Swimming Pools. 1kg 50 x 20g Spas Paddling Pool Hot Tub Chlorine Tablets

Very good and cheaper than others seems to do the job .

Awesome perfect for my hot tub

Bought to revive my hot tub after not using it for the past few weeks after running out of chlorine granules (filter left running). These multi function tablets brought my hot tub water back to life after going slightly green and having a bit of a bad smell! After leaving the tablets to get to work in the floater for a few days we enjoyed the hot tub once again (and in minus temperatures)! I can see these tablets will last sometime and they are also much easier to use than granules as you pop a couple into the floater and leave it to work it's magic rather than adding the chlorine once a day along with any other chemicals you need. I shall definitely consider purchasing these again when I run out of them.

Good size tablets that last a long time in floating dispenser helping to keep pool nice and clear.

Why can’t they ring the doorbell on delivery, too much of a rush?

Perfect for keeping the water in the ice pool fresh.

Fast delivery excellent item

I have tried several tablets over the past few years, including these ones and I go back to them every time as they are excellent and keep our hot tub crystal clear. Highly recommend
