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

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.

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.

The packing doesn't give any guidance on dosing beyond "a couple of cupfuls for your spa" which isn't helpful if you've got a pool of any kind. On the manufacturer's website they've responded to questions with some guidance. They've stated 2 capfuls per 1000ltrs. Most spas are between 750ltrs and 1500 ltrs so that kind-of makes sense. However, they also state 2 capfuls is 50ml. I've measured 2 capfuls of the 5ltr pack with very accurate scales and it's more like 30ml so their advice isn't great.I landed on: 30ml per 1000 litresExample: for my 35,000 litre pool I'd need 30ml*35 = 1050ml (i.e. 1 litre). However, I rounded down to 700ml to be conservative and squeeze 7 doses from a 5 litre pack.

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

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 🎩

Great stuff and better value than the leading competitor

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.

As stated and does work just needed more as have a bigger pool than a spa or hot tub
