Clorox® Pool&Spa™ Swimming Pool Algaecide and Clarifier, Prevents and Treats Pool Algae, Clears Water, 128 Fl Oz (Pack of 1)

If you have problem with allergy or your pool looking slimy looking this is the wonderful stuff makes your pool Crystal clear and I will promise you that I don't buy allergy killer or any of that stuff cuz it was not working chlorine everything was spending more and more money on all of it I bought this stuff the next morning it was all gone and I've not had it back over 7 months and it only uses a small amount well worth the money trust me

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

Product worked amazing by the next day. My pool was green, couldn’t see the bottom, by the next day, it was blue and clear. Easy instructions to follow, made my pool clean and algae free.

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

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.

If people are complaining this doesn’t work, it is because they have a different issue than this is meant for, or they are just not doing it right/lazy. It also needs a few days to work, and kept up on. It works for the mustard algae. Not sure about black or red, I don’t have that issue.I suggest buying two of these jugs right away. Wait until early evening. Pour a whole container in (spread out amongst the pool, pour some directly in the skimmer too) and sweep your pool really good. Get all the green. Read the instructions. Get your ph correct and then Shock the pool. Put a pack in, wait two hours and put another one in. Run the filter over night. Give it a couple days, and you will probably see some algae growing in the spots you missed. Sweep again and make sure to get those spots. Be sure to get into all the nooks and crannies with a smaller brush too (do it right! If you don’t it will just multiply) Put another half a container in and another shock pack. After a couple more days, clean your filter since all that dead algae will be in there.After that, it is just maintenance. I put about a 1/4 bottle in each week along with my other chemicals. This is pretty standard procedure for ‘sanitizing’ a pool of green. If you do it right this stuff works. I have no algae growing in my pool and it is crystal clear. And I have a dog that runs and jumps in with dirty paws 18 times a day…but still no issues staying clean.

Great Product! Keeps my pool clean of algae!

This product is not as good and effective as HTH 67084 Swimming Pool Care Algae Guard AdvancedThe reason I bought this is because the one I buy wasn't available, so I tried this. I thought the price was amazing until I got the bottle and read the instructions. Per the label it states to use the ENTIRE bottle. All 128oz .... I thought, "Oh come on, I don't need to use the WHOLE bottle" - so I tried to use it like I do my HTH product. It didn't work at all. So I had to add the rest of the bottle a day or two later. This just isn't for me.I like buying the 32oz, only having to use 2oz weekly and having a bottle last me longer than a day and the cost of the 32oz, here on Amazon, is worth it to me. Granted the clarifier is separate and a separate cost, but I don't usually need a clarifier - so again, this way is best for me.However, if you prefer all in one and have a place to store a few bottles of this, it might be a good product - since I didn't use it as it stated, I can't say how well it actually works. Maybe if I'd poured it all in at the same time things would have turned out differently, but I can't honestly say
