  • Works great!
Style: XtraBlue Algaecide
I had no idea what type of algae was plaguing my pool, so I bought this because it kills 3 types. My pool is roughly 28,000 gallons and I only used 1 bottle to treat it. Within 10 minutes the algae was gone! 24 hours after application and my pool is back to it’s sparkling clean self! Followed directions exactly as written. I will be using this next spring when we open it up! ... show more

  • Amazing Product Simple to Use
Style: XtraBlue Algaecide
simple to use product that clears algae and keeps your pool sparkling clear. this product is the BEST. with record heat this summer this product will get rid of your. algae and keep your pool looking great. Don't spend a bunch of money on different algaecide products to get rid of any algae you may have. this one product will take care of it. use initial dose and then around 8 to 10 ozs. weekly and your pool will always look great and you'll be saving money in the long run. I tried so many different products and a ton of money and nothing worked as good as this product. this is the best pool item you can purchase to keep your pool looking great with no odor. have been using for the past 2 years and very well worth the money spent. you will save in the long run using this product plus it is the best out there. ... show more

  • Wow!!! This stuff worked great!
Style: XtraBlue Algaecide
I was having problems keeping algae out of my pool for the past few weeks. I tried everything that I knew to do. I finally decided to try an algaecide and took a chance on this one. Dumped 1/2 bottle in late afternoon/early evening and left the pump running all night. I was totally shocked when my pool was crystal clear the next morning. It's now a couple of days later and everything is still great. Can't recommend this product enough. ... show more

  • Life Saver
Style: XtraBlue Algaecide
I was at my wits end trying to remove the yellow algae from my pool. I had tried other algaecides but none did the trick. This Clorox algaecide came to the rescue and removed all of the yellow algae and a little green algae in some of the cracks. Now, my pool walls look back to normal. Buy this brand and this bottle, it saved me from further headaches and from calling a "pool pro". ... show more

  • Loose cap
Style: XtraBlue Algaecide
I love this product, however it came damaged. It leaked so I only received about half the product. There needs to be a better way to ship, where the product stays intact.

  • So very thankful I tried this product!!
Style: XtraBlue Algaecide
I used another product from HTH for the last couple of years and always had problems with algae growing on the bottom and walls of the pool despite constant vacuuming and shocking. When I ran out this year, I decided to try something different. This stuff is an absolute god-send and so much better than the HTH algaecide. I add a 2 ounce maintenance dose once each weekend and the water stays crystal clear without any algae build up at all. So very happy I switched!! Life is soooo much easier and enjoyable this summer!! ... show more

  • Keeps algae at a minimum
Style: XtraBlue Algaecide
I like this brand. I have a darker bottom pool so it stays warmer. I use this algicide and it keeps it under control.
