ClearwaterWater Clarifier for Hot tub Spa and Swimming Water Treatment for Pristine Crystal Clear Water, 1 Litre - Bottle Cover Design May Vary

Excellent product. Put in hot tub 24 hours later really sparkly clear.

This clarifier has made a huge difference to our hot tub water. It was starting to look a bit cloudy, but after adding this, it cleared up really quickly and left the water looking crystal clear again.Super easy to use, with clear instructions on the bottle. A little goes a long way too, so the 1-litre size lasts ages. Definitely a must-have if you want to keep your spa or pool water looking clean and fresh.

Does the trick (just make sure you back wash filter are water has cleared!) Once marking it down one star as it could do with being more concentrated. For a 18x9ft pool (15,000L) I needed 1/4 of the bottle for just one dose. It refers on the back to a weekly dosage. I’ll certainly just be using as and when needed, be buying a new bottle every few weeks otherwise!

Useful essential

Really simple to use for small spas keeps the water clean and fresh for multiple uses it’s now so easy to have perfect water!

Not a very good product i have found and wouldn’t buy it again doesn’t really work that well as it hasn’t cleaned the algae from the pool

Our new hot tub started to look a little cloudy so ordered this....and it's simply great! PH levels didn't change either so very happy with this product. 5*

Fantastic stuff - clear is the way forward 😉
