5.0 out of 5 stars Brilliant stuff what a difference
By Sarah Joy on 25 June 2018
Left it a few weeks before doing review . What a difference this has made I'm in to week 4 of not changing water. As long as you have the ph+ and chlorine levels right this works a treat . I've gone from emptying the spa weekly to not having to at all . As u can see in the pic it's as clear as the day I filled it

5.0 out of 5 stars Wow, great product!
By Amazon Customer on 31 May 2021
This is amazing stuff, after reading the mixed reviews I thought I'd give it a go, as newbies to hot tubs you rely on the reviews to see what works, I have to say I was sceptical but wow!! I've gone from having green cloudy water to crystal clear water in a few days, as you can see from the photos you couldn't even see the bottom of the hot hub before, I added one cupful to start (hot tub is 780l) and then added another cupful after 24 hours and changed the filter, you need to be patient as it won't happen over night, but this stuff does work! I'm still amazed at how clear the water is, I'll certainly buying again

I bought this as I was sick of cleaning my tub every time someone used it. I’m so glad I did as this has made my days soooo much easier, as you can see In my video and photo uploads. It is amazing stuff and if anyone is thinking about getting this I would definitely say get it as you won’t be disappointed. I recommend this product 100%. 😊

5.0 out of 5 stars Does what’s it says on the bottle.
By mc_lukus2 on 27 June 2022
Picked this up due to murky hot tub water (despite being treated correctly), probably as a consequence of 3 grubby children just to see what it would do. After 2 days the results are clear, water looks shinier too. Minimal amount once a week should mean a bottle will last the summer and no waste of water. Recommend.
