20 x Aquasparkle Fusion Shock Hot Tub Pool Spa Lite Oxidiser Clarifier Rapid | Lite, Clarifier, Rapid

We use these to shock the hot tub and they are a really good and convenient way to dose the water. Worth the spend to keep your water nice - look after your water and your water will look after you!

So easy to use and kept pool clear for ages , bought again

This product is absolutely brilliant. Obviously this product will only work if you do general maintenance of your water by keeping the PH levels in check ect.... you can't expect a miracle if you have never maintained your water and think chucking a sachet of shock will resolve everything. All in all great product and works really well if you are already doing light maintenance to your water.

Great product really works. Don't worry about working out the correct dose lob the whole satchet in. Wait 3/4 hrs super clean water. No maths involved if any says different there lying. Easy peasy. My only critasim it's a little on the expensive side.

So easy to use, no second guessing with chemical quantities. Hot tub always looks clear and inviting!

Didn't feel it did the job efficiently enough.

At first I thought this had not worked. The water is only 3 weeks old, it went cloudy because it had been left for 2 days unchecked. I bought this to prevent a refill, but 24 hours after putting it in, it was clear. I was just about to empty it too. I am pleased this worked. Great product.

if you need your pool quickly and need to remove any pathogens from the water to make it safe to splash around in this is perfect. Should be safe to use in around 2 hrs, then you can use a Chlorine filter floating in the water. You can Google this all and educate yourself on the need for it
