Am glad I bought this brand. R ### ⭐⭐⭐⭐⭐ it is effective *by S***L on July 31, 2025* This product seems to work well for our hot tub. We have difficulty keeping or getting the Ph low enough, but adding the recommended amount now and then makes a big difference. Between this and changing our filters, our slightly cloudy water becomes clear. It's easy enough to use, and it's worth the cost. It will last quite a while (and then I'll buy some more.) ## Frequently Bought Together - SpaGuard pH Decreaser - 22 oz - SpaGuard Balance pH Increaser for Spas & Hot Tubs, 18 oz (1.12 lbs/510 g) - SpaGuard Spa Total Alkalinity - 2 Lb --- ## 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.co.uk/products/14453302-ph-decreaser-22-oz-single-pack](https://www.desertcart.co.uk/products/14453302-ph-decreaser-22-oz-single-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-28*
