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

Works well and the 5 litre container is great as it lasts a good while.Definitely a product I would buy again

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!

First time I used it I put more clear water in then I should. Read the instructions and hey presto.

I’ve been using this for several years after trying other brands without success. Just a splash turns cloudy water clear again after the overnight cleaning cycle. Just make sure you clean the filter afterwards.This product has vastly increased the time between water changes, so is worth every penny.

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, unbelievableHave 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 !!

I don't often write reviews and when I do it's rarely about chemicals to put in a hot tub. However, this stuff is great. I've not seen anyone else leave a review concerning an inflatable hot tub so thought I'd chip in.As you can see from the images (sorry that the first one is a bit blurry), the difference speaks for itself.I've got a Lay-z-spa Paris and despite using Clearwater Clarification liquid, the hot tub was remaining murky and had a greenish tinge. I'd cleaned the filters and been pretty militant regarding the chemical routine etc. I live in the East Coast of Scotland and we're blessed with some of the cleanest / freshest water in the UK, so I was disappointed that the hot tub kept clouding over.Prior to using this, I checked the levels of PH and chlorine were all ok. This arrived promptly. Was well packaged and after reading the instructions I poured in two small caps worth (there's a little rep cap on the inside of the bottle).Checked it after an hour and it was almost clear again. The second pic I took approximately 24hrs after the initial dose. You can see it's made a massive difference. 5L of this is going to last a long time!It's also worth mentioning that none of the other chemicals seemed to be affected by the Clarifier and the pool looked, smelled and felt lovely and fresh.Really great stuff and I'm going to try out their other products now too.

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.

We had a problem with my old filter pump, so the pool water sat stagnant for a while. This made all sorts of algae and larvae (literally thousands of mosquito larvae!!) grow.I shocked the pool, and the water went cloudy, the new (much more powerful filter) i purchased could only do so much, but the water remained quite cloudy.I used only a little bit (probably 3 lids worth) and within half an hour, the pool already looked noticeably clearer! Must use in conjunction with filter to get all the coagulated bits out.I'm really happy with my purchase, and have plenty left to use for the rest of the season. I've never had so much success with clarifying my 12ft above ground pool. It looks just as clear now as if I had just put new water in.Photo is of the pool an hour after using this product with filter on.
