  • Algae killer and clarifier
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
This is our go to product to clear up algae and make the water sparkle. This product does exactly as advertised. After shock, this clears up all the algae and clarifies the water. There are other similar products out there, but this one seems to outperform them all.

  • Just what I needed
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
Last year I bought a pool and we filled it with our well water it got all slimy and gross within a week I tried to get some pool shock but all that stuff was too expensive. This year I got this and it's kept my pool clean for over a month now. Was very well needed and my kids love how clean the pool is now ... show more

  • Works well
Size: 128 Fl Oz (Pack of 1) Style: Pool Algaecide
This stuff is a pool life saver. It helps kill and control the algae in my ungrounded pool. I use half of it at a time in a 13000 pool. I use it with my shock and tablets and it works for a month or more for me. It takes about 24 hours to notice a difference in the water color. Its simple you jist take the cap off and pour it in. It doesn't seem to have a bad smell ether, just remember to wash your hands when done using 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

  • 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
