Hardware Store selling CYA Remover

[chem geek]

There are several threads talking about CYA Remover including this one. Since the ingredients are not listed on the product we can only speculate what it is, but strongly suspect that it is just melamine. Melamine is the same chemical you add in the CYA test that makes the water cloudy when CYA is present. Technically, it precipitates CYA and though your filter will hopefully filter out much of the CYA, your pool will likely be very cloudy for quite some time using this product. At least that's our best guess at this point in time. You're welcome to try it and let us know if it's a disaster -- just kidding.
