Review: A very good product does exactly what it says and keeps my water crystal clear Review: Actually got this to use in my Bestway outdoor pool, rather than a spa/hot-tub. The pool is 13ft diameter, and all summer season I try to keep the water clean using chlorine, anti-algae etc. Now and again the water does get cloudy so I use this product. I worked out capacity of the water in the pool and calculated the required dosage. When added, I let pump run a good 4-5 and then left it overnight. In morning, water was noticeably cleaner & clearer. After running pump another 1-2 in the morning water was perfectly crystal clear. Would recommend. ## Features - Transforms dirty and cloudy hot tub water to make it crystal clear in no time! - The unique formula works to bind small particles of dirt together so that your hot tub's filter system can filter them out - leaving your pool water clean and clear - There’s no fuss or mess with this easy to use product.

Would recommend. ### ⭐⭐⭐⭐ Review *by T***5 on 20 July 2021* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/327418908-spa-water-clarifier-transforms-hot-tub-water-from-cloudy-dirty](https://www.desertcart.us/products/327418908-spa-water-clarifier-transforms-hot-tub-water-from-cloudy-dirty) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
