Yellow Out Swimming Pool Chlorine Shock Enhancing Treatment - 2 x 4 Pounds

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.

I've used Coral Seas Yellow Out over the years with a lot of success. The most recent time I didn't follow the instructions to the letter and it didn't work. At all. If you want this product to work, FOLLOW THE INSTRUCTIONS. If you do, you'll be happy with the results. Learn from my fail.

I was getting frustrated with not being able to keep my pool clean I tried everything under the sun to get rid of the algae to no avail a co worker mentioned this and I said ok I used one container of yellow out in my 16x48 above ground pool and man in 24 hours my pool was blue not green the water was cloudy for a few days it has cleared and myPool is still looking great after two weeks I will def buy again

Yellow algea had been showing up in our pool about every two to three days after cleaning. Had never had it prior to this summer. Started in just a spot or two then became where it was in about 6 or 7 spots and looked terrible. I tried everything. Finally bought this product. Followed directions and put in pool about 2-3 weeks ago and have not seen any yellow algea since!! It has been a 5 star for sure, so far anyways!

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.

Product seemed to work well in clearing up yellow green algae. Have to use a lot of chlorine before using as it uses up significant amount of chlorine in the water.

When my pool turns green from Florida rain, or other chemical imbalance this product along with a jug of chlorine returns it from green to blue within the hour of application.

I loved that it did as advertised and made my pool crystal clear ( yellow all gone ).
