This product
CLOROX Pool Phosphate Remover 1 Quart removes 2,000 ppb (2 ppm) of PO4 from 10,000 gallons. That's usually less than 1/2 what Phos-free does costs, per unit of phosphate removed. It seems to be slow acting, so if you test immediately, you won't see much reduction.


WRONG: 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!


The Orenda PR-10000 product removes 5x that (10 ppm per 10k gal) per quart, so if you purchase it for less than $70/quart it's even cheaper. But you have to be careful with it, or it will cloud your pool.
