Phosphate testing

[Big Splash]

Turns out the Clorox phosphate remover is a seriously bad deal. A quart of the Kem-Tek predecessor product was labeled as removing 2 ppm PO4 from 10K gallons; the Clorox product is virtually the same price, but only removes 0.75 ppm from 10K gallons.

That means the Clorox product is actually 267% more expensive!

Well now... I did notice the "Clorox" brand is actually licensed by Easy 123 Pool Care LLC (whoever they are) on this stuff. I wonder if Clorox knows they're deluding their good name..

Any good alternatives? Is PhosFree a better deal?
