This worked perfectly! ### ⭐ HCD-55 doesn't produce ozone. *by N***S on March 30, 2025* Ordered the HCD-55 as a replacement ozone generator for my hot tub. It did not produce any ozone light comes on nothing happens. So I thought i received a defective one so i requested a replacement. The replacement did the same thing. the light comes on but nothing happens. After looking at this unit it runs on normal 120/240 volt connections so all your hot tub controller does is turn it on or off. So I know it was on and working based on the light. I did test a little further by using a 4amp female connector so I could plug it in separate from the hot tub controller and it did the same thing. If you look at where the ozone exit is there is an intake right next to it and it is in the same little box as the exit so i am not sure if this thing could ever actually work. Both the intake and exhaust are in the same place even if it actually produced any ozone, it would take the lease path of resistance go out the intake. I would not suggest purchasing the HCD-55 based on my experience. ## Frequently Bought Together - HCD-55 Spa Ozone Kit Suitable for All Hot Tubs & Swim Spas, Hi-Output Spa Ozone Generator with Capacity of Up to 1500 Gallons, Universal: 120V/240V - Leisure Time 22339A Spa Up, pH Increaser for Hot Tubs, Prevents Corrosion and Equipment Damage, Compatible with Various Sanitizers, 2 lbs - EASYTEST 7-Way Pool Test Strips, 150 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine --- ## 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/602518423-hcd-55-spa-ozone-generator-110v-plug-for-hot-tubs](https://www.desertcart.us/products/602518423-hcd-55-spa-ozone-generator-110v-plug-for-hot-tubs) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-23*
