Clearwater Water Clarifier for Hot tub Spa and Swimming Water Treatment for Pristine Crystal Clear Water, 1 Litre

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.

Arrived yesterday, put a 3 cap fulls into my 400L cold plunge (~13ml, a per bottle).Tub was a bit murky despite chlorine shock, algaecide and new filter, so thought I’d try thisWow! Works great - 12 hours later it’s crystal clear!!Worth buying and will last a long time.

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!

Works as described. My spa water was very cloudy and looks dirty so I sought about draining it completely. Then I found this product so decided to give it a try. I've added chlorine + this liquid and left circulation pump working. 24 hours after water in my spa looks crystal clear again :) I'm super happy with the results!

Very nice and like chemicals for water.

Product is fine, does what it says on tin. Delivery driver didn't even chap door nor follow instructions. Luckily a neighbour spotted our package. Will be buying in store from now on as Amazon going downhill recently

the reviews were good so thought id try, and was really impressed. Will buy again

Having read the reviews I expected it not to work. I added the required amount it didn't seem to work so I prob double the amount. (Then I ready add too much can make it cloudy.) I ran the jets for about 20 mins and there was no change. I left it filtering for 24 hours and expected it to be the same butcto my surprise it had worked. So pleased with this as I'm on a water metre so filling it cost me! Just allow it time and clean the filter once it's cleared. Also I made sure all my levels were right before I added it (alkalinity, PH and chloride) I also bought the scum collecting balls but they don't look any different so I don't think it was them.
