I think! For those horrible back spots *by S***. on Reviewed in the United States on July 2, 2019* We were battling and battling these black spots that showed up on every scratch and ding on our hot tub. It was so gross.. I had to get the heater fixed and the spa guy recommended this product. In the instructions it tells you to bring your PH level to zero... when we did this.. the black spots disappeared before we even used the product. Used it anyway and we haven't seen anymore (we're keeping our PH levels low now).. so.. I think it works! You have to do your math though.. the bottle is for treating a swimming pool.. not a spa. For our 300 gal spa we used Tablespoons. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars STUFF IS AMAZING!!! *by S***M on Reviewed in the United States on August 4, 2017* BUY THIS!!!We had dark colored stains all through our hot tub. We thought it was algae, even though it made no sense. We keep our hot tub chemistry perfect, so no algae should be growing.We regularly drained the tub to get in there and scrub the stains away with *lots* of elbow grease.The wife found out what we were going through is actually called "cobalting", so I ordered some of this.Dropped the pH to get the alkalinity down to 0, added a little bit of this stuff, the BOOM: stains gone!Ain't Chemistry fun? ### ⭐⭐⭐⭐ 4.0 out of 5 stars Four Stars *by D***O on Reviewed in the United States on January 18, 2016* this was a reorder- it works --- ## 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.tn/products/45953841-cobalt-cure-cc-c12-2-lbs](https://www.desertcart.tn/products/45953841-cobalt-cure-cc-c12-2-lbs) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-25*
