OPC 5kg Stabilised Chlorine Granules - Swimming Pool Chlorine Sanitiser

Great value for money. Very easy assembly. Good quality - especially for the price.

Cheapest online chlorine granules I could find. Seem to work OK, but the granules are not as pure white as those which came with my new hot tub.This is probably not an issue, I don't think it will discolour the water but I can't tell yet.

Good quality chlorine and great service from this supplier

Cheap and effective in my hot tub - great product

Good value, does what it says on the tub.

Never used these before. Usually use a well known brand. These do the job perfectly. I don't need to add as much as I do with the others. It helps maintain the ph and alkaline levels. I've only needed to add the weekly dose of algacide

Good strength chlorine granules mixes easily has kept my pool sparkling all summer

Has cleared my pool after winter ravaging.Good product.
