1kg Granular Shock Treatment Hot Tub Spa Swimming Pool Chlorine Oxidiser

Took a while to arrive but worked as expected.We now have a nice clear pool.

Bought our first inflatable hot tub and used this to boost the chlorine levels on first fill. It immediately lifted the levels for safe spa use using the correct dosage on the label for the size of our tub. I will use this once a week as our tub is being used by a family of seven every day. I use a jug and fill it with water directly from the tub. Then add correct amount and stir for a few minutes. Dissolves easily and works great.

If you are using in a hot tub - I would strongly recommend going on a supplier website eg Lay-z-Spa to calculate safe /accurate dosing for your capacity spa. The instruction on the bottle are woefully inadequate.

I’ve used half of cup for my 8ft x 0.76m pool and it's worked brilliantly. Thank u

I ordered this as a last ditch attempt to clean a 10ft above ground pool. I thought the water was beyond help as it was green with algae. I used the pool shock as per the instructions and to my surprise woke up to clear water the next day. Sadly the water was already full of mosquito larvae so could not be used, however when I refill I’ll ensure to use the pool shock regularly so that I don’t have the same problem again.

!HONEST REVIEW!Brought a house and got my hot tub serviced. I had got recommended this product from the service provider and never looked back, never had an issues!

I have used algae products and other products with no success ,so ordered this .I mixed 100g to half pint of water for my 660ltr hot tub ,I was dreading it has it was cream in colour , 24hrs later I had a clear sparkling hot tub , amazing shock will purchase again

Took over half of container to shock are 16ft pool and bring levels up to desired readings
