ULTIMA-PLUS XPSpa Water Clarifier - Transforms Hot Tub Water From Cloudy and Dirty to Crystal Clear - Suitable for all Hot Tubs, Spas and Pools (5 Litres)

Added the recommended dose and needed 2 x 8 hours cycles before the cloudy water had completely cleared. I did this alongside a chlorine shock on my hot tub, but it worked and was using the tub the next day.

Sorted my hot tub cloudiness in just 2 doses, this stuff works, brings all the particles out and they clump in the bubbles and enable you to skim off the top.

Well it definitely works as advertised. I would advise that if you use it in a spa (1200litre) then I would use a little less than recommended. Be prepared for the result. I would suggest using a spa net to remove some of the big collections of residue. Other than that it works very well, and with the size of the container it will last for some time. This is well value for money.

Does exactly what it says it does

Added to our tub as it was was murky after 3-4 days going cloudy? Was advised to buy some of this stuff and still same m. So it’s a thumbs down from me

I did buy this without reading the reviews first (D’oh). Used for 1st time and it actually made the hot tub worse. I then left this for a day and looked again, still cloudy but not as bad. Used another 2 cap fulls and left for another day.Thought it would be as bad, but actually really surprised, worked well. Yes there is a small smell, but after a day you can’t tell.A great item to clean the water will definitely buy again in a year once this is gone.

Spot on

Added 50ml to my cloudy hot tub water. I let the solution work for 10minutes then scooped out the clumpy dirty foam. Really pleased with the results.
