What's wrong?** A: Hi on starting up you need two tablets . Then on a weekly basis you need one . It can take about ten days for two to dissolve and then one usually takes a week . When we first used it it was a little foamy that goes away after a week . We have had know problems with only one tablet a week the water is crystal and doesn't smell to strong . We also change filter once a week same day as new tablet . Hope this helps . We use it every day . **Q: I still have not received my parcel how can I get a refund?** A: Contact Amazon live chat ## Frequently Bought Together - Clearwater 1 kg Multifunction Chlorine Tablets, 4-in-1 Dispenser Tablets (Sanitiser, Stabiliser, Algaecide and Clarifier) for Pools and Hot Tubs, 50 x 20 g, White (1 kg) - Clearwater Water Clarifier for Hot tub Spa and Swimming Water Treatment for Pristine Crystal Clear Water, 1 Litre - Clearwater Hot Tub, Pool and Spa Test Strips x 50-3 in 1 - Measures Chlorine, PH and Total Alkalinity --- ## 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://macau.desertcart.com/products/48080983-clearwater-4-in-1-chlorine-tablets-for-hot-tub-spa](https://macau.desertcart.com/products/48080983-clearwater-4-in-1-chlorine-tablets-for-hot-tub-spa) --- *Product available on Desertcart Macau* *Store origin: MO* *Last updated: 2026-08-27*
