Clearwater 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

The tablets seem fine. They fit in the dispenser OK and last as long as the previous brand I used. I only need to use 1 per week so it's difficult to be more detailed with the review. I'm happy with the purchase overall.

I've tried a few methods and mix of chemicals to keep our easy set (10ft) pool clean. These are by FAR the easiest and best way to keep the water crystal clear. Long lasting and simple to use. Have genuinely recommended these to friends.

Great product you always know the chlorine level

Using it for our hot tub, appears to be working fine.

Great price essentials

effective and long lasting, kept my hot tub nice and clean

These tablets have saved so much time mixing chemical. We have an 800L (6 person lazy spa) hot tub and one of these tablets does the trick in the slow dispenser.

Excellent product
