This non-foaming, non-staining treatment clears algae in 24 hours and works great in all pool types. Use as a preventative algaecide weekly if your pool is prone to algae or when the temperature increases during the peak of summer. Always apply chemicals according to label directions. Circulating pool water when applying chemicals helps disperse chemicals throughout the pool for maximum coverage. Review: A case for Clorox All-in-One Algae Killer over Yellow Gone/Out - This product worked in a quick, fantastic manner. After 24 hours, a noticeable clearing was taking place and within 48 hours water was completely clear. I had used 2 applications of Yellow gone/out but each time the yellow algae returned. Also, Ai stated that yellow gone/out was a better product because it was a different active chemical. The thing about yellow gone/out is it eats a lot of chlorine to kill the algae. On both applications of yellow gone/out, I dumped 6 gallons of liquid chlorine. This product being a different active chemical did not consume one half that amount of chlorine. I also had some metal staining and this Clorox product lessened the color whereas Y O/G did nothing. One strong word of caution, once added to pool water, use your brush to ensure it does not settle along the edges and corners or it will definitely lighten a liner pool. Do this even though you run your pump/filter for the full 48 hours. Review: Best algaecide on the market! - This is the ONLY algaecide I use! I have tried several over the years and it was always a fight to keep my pool clear(24×52) This does not foam, just pure clean. I put in .5 ounces twice a week around the edge of the pool and have ZERO algae issues with a pool in full sun and a yard full of trees. The copper in it is the vital ingredient to keeping the pool in check! ## Features - All-in-One Algae Killer: Clorox Pool&Spa XtraBlue Swimming Pool Algaecide kills algae in just 24 hours.

Will this take care of that?** A: Hi, We are the manufacturer of Clorox Pool and Spa products. This algaecide is a great algae killer. It will need the assistance of chlorine and the pH will need to be in the proper range. If you have any other questions or concerns, please give us a call at 1-800-SOS-POOL. **Q: Is this safe for saltwater pools?** A: Yeah, It's just shock. Saltwater pools disinfect the same as any other pool it's just that the chlorine comes from salt in the water being broken down into Chlorine and Sodium by the saltwater element in the piping. **Q: Can I use this in our coleman above ground pool?** A: We have an above ground pool that we use it on. Not a Coleman pool, it's a much older pool that we have had more than 15 years. The last liner replacement was three years ago and we've used this product on our liner without any noticable damage from this treatment. Hope this information helpful. **Q: I am looking for a product to prevent mustard algae. How many ounces of this would I need each week per 10K pool gallons?** A: My pool is 15' x 30' w/7' deep end, I use 8oz every other week and live in South Florida where the sun & humidity can wreak havoc on a pool. I also use 1 lb. of 4 in 1 shock (15 min to swim) every other week. My last part of my regimen is 2 capfulls of Phos-Free evry other week. Sometimes I forget and go 3 weeks between treatments. The worst I get is some black algae in the upper tile grout by the coping and very light green algae on the walls that brushes off. My water is crystal clear and always tests good at the pool store. I have been following this regimen for 12 years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A case for Clorox All-in-One Algae Killer over Yellow Gone/Out *by G***R on 8 July 2026* This product worked in a quick, fantastic manner.
