Natural Chemistry Yellow Out Swimming Pool Stain Remover, 4 lbs

Yellow out is a must have during the summer to keep our pool clean and blue. In the past, we struggled with algae that you couldn't vacuum up in the pool. As soon as you neared the algae with a pool vacuum it would spread in the water like powder. Yellow out has been a miracle. We were able to get rid of our mustard algae. We keep a container of this on hand. This is a pool staple.

I was very happy with this product as I needed to clear up my pool and it did the job well. The price was acceptable and product had directions that were helpful. It was shipped and received in a fairly short time. I'll purchase it again, If necessary. Will recommend it to others

It's a great product at a great price.

this product works very well.

After using this exactly as instructed, it did not work. Save your money and buy elsewhere. I will not use this product again.

Pool stayed green. I have used yellow treat prior and will only use it again never another type. Unfortunately this was a waist of money.
