Removes phosphates from water. These phosphates are generated in greater quantities in pools with saline electrolysis or active oxygen, so we recommend analyzing their concentration at the start of the season with the phosphate kit and if present (more than 100 ppb), treat with PM-625 PHOS-OUT. This will make pool maintenance easier for you.
Initial use dose (=500 ppb): 0.6 L/100 m 3 .
