5L of Pro-Kleen Spa Clarifier - Achieve Brilliant, Sparkling Water - Improves Filter Performance & Efficiency

This product is amazing. It does exactly what it says, it drastically improved the water on a 20 min full jet cycle. I ran a second cycle and the water was crystal clear. Just be aware it will bring up alot of scum that may make you wish you had bought it years ago! Will certainly continue to use this and buy more in the future. You only need a small amount for excellent results so the bottle will last a long time.

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.

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

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!

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.

All pro-kleen products i’ve used work very well and the price is not expensive.

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.

OK, as every hot tub owner knows, every now and then the water will go a bit 'cloudy/miky', no matter how careful we are with balance/clothing etc. We had some friends over last weekend and by the Monday the water was very 'milky'. Read the reviews on this product (as have used a number of so called 'cleaners' with little/no effect), so thought we'd give it a try. All we can say is WOW !!! Put just a tad over 2 CAPFULLS in last night, left on overnight to run through, came down this morning and it looked like I'd just filled it !! Clear as a bell, sparkly, with that blueish (clean) tinge, unbelievable Have to admit that this product is a game changer, it hasn't affected the levels at all but cleared the 'milkiness' 100%. Wish I'd taken a before and after, as honestly it worked.... It WORKS and if 1st treatment is a guide, this will always be the go to product. BRILLIANT !!
