Product worked great. However took about three and a half weeks to arrive from amazon. So you can imagine I had a mustard pool for much of the summer. So much for getting it cheaper on Amazon. Oh also I didn't need two containers.

Make sure to follow proper sequence from pool company on how to restore pool water to proper settings. But this product works great!

After spending countless amounts of hours cleaning, scrubbing and dumping expensive chemicals into the pool, none of them worked. So i decided to try this stuff and man does it work. You couldn't see the bottom of the pool before i put this stuff in. I follow all the instructions and 24 hours later i could see a patch of algae that gathered in the center of the pool but the rest of the water was clear. I can see the bottom again.

Love this product for my pool. Had a hard time keeping the green off the sides and bottom. Once I treated with yellow out it cleared right up and has been back for a month. Great product.

Good product with a dumb and misleading name. If your pool was neglected and it's green then buy this. It's awesome.If you have a stubborn mustard algae problem despite keeping your chlorine level up, don't buy this. It's worthless. Instead buy Yellow Treat, which is an awesome product for that.But Yellow Out is da bomb for green pool algae cleanup.I'm giving it 4 stars instead of 5 because its name doesn't match its mission.
