I previously bought the "branded" version of these which were combined with other minerals to keep the spa running well (or so I thought...). The branded version chlorine was fine but the other chemicals did not dissolve in my hot tub and left a sandy residue. In addition, the branded tablets also clogged up the filter with what I can only describe as cloudy snot which required daily rinsing.These tab do what they say on the tin. Chlorine to dissolve slowly in your dispenser.. Recommended!

great chlorine tablets, good value for money - tablets will last a long time, purchased for a large paddling pool. has a nice chlorine smell, but not too strong and keeps the water clear and fresh. I would recommend. pot is a large pot of tablets so will last the whole summer and prob the next one too.

Fab customer service after a little hiccup with the delivery company (our area was having issues with deliveries not turning up and being delivered to the wrong address or stating it had been delivered when it hadn’t) I contacted the seller who was very quick to respond to my messages asked if I could just leave it a couple more days and if it hadn’t arrived he would send out using next day with another courier which he did in the meantime the pool did go green fairly quickly but once arrived we gave a shock dose and it came back clear within 12 hours these tablets have been amazing, value for money and work loads better than the chemicals/and liquids you have to measure, 3 days after receiving the replacement the original order turned up after Hermes had stated I’d signed for it and it had been delivered 11 days before I messaged the seller to see about returning and he kindly said to keep them for the inconvenience which I really appreciate thankyou very much for you quick replies and also resolving the issue

Well packed in safe container. Easy to use in Hottub to maintain perfect ph levels for safe usage

We have been using these tablets in our water feature to keep it clear over a couple of years. The tablets work very well. When the water is well circulated they keep the pebbles clean and the water crystal clear.
