    This stuff is the best!!! I usually fight a cloudy, green pool for days in the summer, but this stuff is amazing! Clears the pool overnight and, since it's concentrate, it doesn't take a lot to correct the pool. Love, love, love it! So glad I discovered this product.

    Pool chemicals were balanced, plenty of free chlorine but the water was cloudy. Don’t know what the problem was but two applications of this and the water is crystal clear again. Excellent product and you don’t need much for each dose - there’s probably enough in the bottle for an Olympic sized pool! (Well, maybe not quite that big…)

Product description

"

Polysheen Blue is one of BioGuard's most popular products for keeping your water looking crystalline. It uses special polymer technology that allows it to both gather unfilterable microparticles and remove them from your water. Polysheen Blue also helps maximize the life of your filter and is a product that is fantastic for problem solving and maintenance!

How to Use: Pour recommended dosage of Polysheen Blue around the edges of the deep end of the pool with the pump running

Pro Tip: You can overdose on Polysheen Blue (which may make your water cloudy)! Make sure to follow the recommended dose and do not add the recommended dosage more than once every 72 hours!
