Fantastic Blue Stuff

Have a 13 year old vinyl pool liner that had become increasingly stained on the bottom and sides. Always looked dirty and very unappealing. Found this product thru the wonderful customer service person at Jacks Magic. He recommended Pool Geek for the purchase. The initial shot of 64 ounces broadcasted cleared these stains in less than a week. The pool never looked so good. Unbelievable. A maintenance dose of 16 ounces has kept it looking beautiful so far. Pool Geek shipped quick and I will definitely do business with them again.

The Blue Stuff

Our newly replastered pool was filled with our well water. We didn't realize that we had copper and iron in our water and it caused the surface to develop an unsightly light brown stain. We used this product and the stain is starting to fade. It is not completely erased but it looks better than it did. I will put more in next month in hopes that it will be completely gone. I only gave it a 4 because the stain did not completely disappear.

How To Make Stains Disappear.

Added this product to my pool about 2 weeks ago and already starting to see results. Only slight signs of stains remain. Would highly recommend this product.
