  • Amazing results in a little over a day!
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
The algae in our pool was really bad. We kept pouring more and more pool shock in and it would work for about a day. Bought a better pool pump and filter, and still we had algae build up constantly. We bought this Clorox Pool & Spa and after about 36 hours our pool was clear of floating algae, there’s no more algae build-up on the bottom, and our pool is a beautiful clear blue!!! Very happy!!!!! ... show more

  • Absolutely best product I've ever used...100 stars 🤩
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
Absolutely the best pool product I've ever used. I've had pools my entire life. Nothing took a green swamp pool with tadpoles in it to Crystal clear like this did.. And literally started turning within 20 minutes of usage.. Fully clear 12hours...I highly highly recommend this product to anyone with a pool they think they need to drain because it's so dirty... My husband swore we were going to have to drain it ... ... show more

  • Twenty Hours Later, My Mild Problem is Gone!
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
My algae problem wasn't horrible, but it was for sure a daily battle to keep it relatively clear. Every day I had to sweep the entire pool, run the robot vacuum, and the sand filter for 10+ hours! I'm roughly 14,000 gallons. I have a circulating pump running simultaneously with my large sand filter, and during the latest algae bloom I completely gave up on the skimmer and skim by hand with a net instead. I've been shocking every few days, have three chlorine floaters, and still the algae problem persists!.. This is the first time after six years in this pool the problem became unmanageable! After reading many reviews, I just wanted to experiment with an algaecide and found this one the cheapest with next day delivery. Here I am 20 hours later with a perfectly crystal clear pool that I've been known for! If I mast, I'll get some more expensive concentrate, but for now problem solved. :-) Attached are my before and after photos. This is 20 hours into the treatment, I have a few more filter flushes and more vacuuming to go. ... show more

  • Works! Use in combination with a package of shock.
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
Works! I've read the reviews and some not so great. My tip based on research, add a pack of shock when using this product. I kept the pool crystal clear all summer. We traveled for 2 weeks and it rained a lot when gone. Came home to a green pool filled with leaves and debris. My son was in charge and didn't even run the filter. My pool is clear again after using this Algae se with ... show more

  • Just buy it, seriously!!
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
100% buy it!! We were struggling with algae and cloudiness for a month. We shocked, double shocked, brushed, balanced. Pool store said just run the pump 24 hours and it will clear up. We did that for 2 weeks. This stuff made our pool crystal clear in 12 hours. Worked like a charm and wish we had bought it earlier. We will be using this every summer now. Definitely works! ... show more

  • Ok, but not great results. 🙁
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
This didn’t work as well as I had hoped. I have a small pool, 12’ x 24”. It wasn’t terribly green, but enough that I didn’t want to go in it. The Clorox made it somewhat better, but not clear and it still had algae. I put a whole gallon in less than 3000 gallons of water. Either that wasn’t enough? Or it just didn’t do what I had expected. And yes, I ran the pump and cleaned the filter and swept it, a bunch of times 🙁 ... show more
