The purple setting was on 2 and lasted 3 months with readable levels on test strips. I changed it out with this. I've gone up to 6 with no detectable level on water test strips. Should have bought the purple cartridge again. Saw a floater and bromine tablets at Walmart this year in pool chemical area of store, tried 2 tablets in floater set on 1 and, you got it, detectable levels shown! ### ⭐ Terrible! *by K***R on Reviewed in the United States on September 28, 2021* The product is supposed to float upright in your hot tub to help keep it clean. Instead it sank to the bottom of the tub and some of the powder coming from the tube. I assume it is too old and expired. I did not open to use until shortly after the window to return had ended. I will not be purchasing this product from this vendor again. ### ⭐⭐⭐⭐ Works great *by R***8 on Reviewed in the United States on November 25, 2019* Been using these Spa Frogs ever since we got our hot tub. Easy and reliable. Good price on Amazon. I use these with the blue mineral cartilages. Takes all the fuss out of chasing the tubs chemicals. --- ## 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.pt/products/22486496-king-technology-frog-serene-bromine-cartridge-2-pack-01-14](https://www.desertcart.pt/products/22486496-king-technology-frog-serene-bromine-cartridge-2-pack-01-14) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-22*
