Clorox® Pool&Spa™ Swimming Pool Algaecide, Prevents and Treats Pool Algae, Non-Foaming, 1 Quart (Pack of 1)

Ive tried several different algecide brands and none of them worked, I was changing my 400 gal unfiltered waterfall pond every few weeks in the summer - draining, pumping, powerwashing, vacuuming, refill - real painful. I tried this Clorox stuff and the difference is amazing, I'm going on 5 weeks and still super clear. Nothing is growing.Definitely a 5 star!

We have a small dog pool. Great to be able to use small amount and it is pet safe.

This was less expensive and worked much better than what I usually get from my local pool store

is works great in a 15x28 pool the amount it says or a little more. was very happy less colorine less chlorine smell. bigger was not better.

As advertised. Works well

Works good

Great working item

First off, I started having horrible cloudy yellow algae filled water. I basically went out and bought new cartridge filters because I couldn't get it cleared up. I really didn't need new filters but I was desperate.It was around mid april in texas and we were getting tons of wind and rain and it seemed no matter how much I vacuumed the pool I couldn't get rid of the cloudy green water. I could barely see the drains quite honestly. The water looked horrible and I felt hopeless.I had my chemistry in order, but did have higher phosphates than usual at about 750. This was one of those times where shocking wasn't doing anything and I was getting very upset. I NEVER used algaecide in the past because many pool people say it's a waste of money, but in my case it wasn't.I know there is an argument that a phosphate killer is the way to go but I decided to try the clorox product and I'm super happy I did. I poured about half the bottle into the edges of my pool and swept the side walls and throughout the day swept the debris the best I could to the drains. I also put 2 pounds of granular home depot max blue granular shock in the skimmer without the basket.What shocked me was hen I woke up the next day the pool was the blueist it's ever been and was nearly 100% clear! Even my wife was amazed and couldn't believe how beautiful the water looked. I think for a long time I've suffered with yellow algae but have kind of kept it at bay but I've always had dingy greenish water that wasn't that blue. I think what the clorox product did for me was show me that I desperately needed an algaecide in my pool and it was starving for it. It wiped the algae clean out and now I'm proud of how my pool looks for the first time in a long time. I actually think that this product could potentially save me money in shock if I use it as a preventive.Don't listen to the negative reviews on this stuff, I would venture to guess that many of the people complaining aren't using it properly. You have to have a well balanced pool, with clean filtration and some good shock if you're pool is out of hand. Mine went from embarrassing to magical over night with just a little work.Also I got ZERO foaming! I know some people do, but I didn't. One tip, before you put it in or shock your pool, make sure you sweet the side walls of your pool first to get the algae loose so it's floating all around in your pool.. This is what helped my situation. I also bought some flocculant thinking I may need it to clump the particles so I could vacuum but somehow the clorox product and a little sweeping completely did the trick on my ugly yellow cloudy water. Thanks Clorox!
