Consistently good
A must-have for pool or spa. Has helped clear some very cloudy water on a few occasions and saved the day! Have been using this for years. A go-to product.

Outstanding results highly recommended
This product works fantastically, a lot better than the previous brand of clarifier I was using and at the offer price of £15 for 5 litres it’s incredibly cheap. I added this to my pool and within an hour there was noticeable improvement. Within a few hours was looking great. Within 12 hours was looking outstanding. Anyone who is giving this bad reviews probably doesn’t understand pool chemistry or how this product is meant to work. It’s not a replacement for chlorine and proper water chemistry, infact with some types of filters you shouldn’t need this at all. I have a sand filter (with glass media). Generally it’s quite good but doesn’t catch the smallest of particles that end up building up in the pool and causing dull / cloudy water. With this it traps smaller particles and my water is crystal clear!

Great product for a clear spa
Economical as it goes a long way, used in conjunction with other products such as chlorine keeps my spa clean and running well.

Chemical magic
One capful turned my groggy water to crystal clear! Left for a few hours, this lifts all the scum from your cloudy water to the top, forming a "dirty" foam. Scoop this off, let the pump run overnight and your hot tub will be crystal clear. Chemical magic 🎩

This item is good
This is a good product but every now and again it leaves a little gunk stuff in the hot tub when the jets are on.

Crystal Clear Results — Works Brilliantly
This clarifier has really helped us achieve and maintain crystal clear water in our large pool. When combined with careful chemical management, it makes a noticeable difference. Great value for the size — highly recommend if you’re looking to keep your water sparkling.
