CuLator® Metal Eliminator and Stain Preventer acts like a sponge to rapidly remove and eliminate bad ionized metals from pools and spa water. Simply place a pre-measured PowerPak in the skimmer basket. As water passes over the PowerPak, metals attach to the CuLator® and are trapped inside the bag. After use, toss in the garbage and the captured metals are eliminated from the water. It's Easy!
(PowerPak after use with iron bound inside)
Hold the PowerPak up with light behind it to see if there is any color change. The color change comes from the metal bound to the polymer inside the bag. This bound metal does not release back into the water.
NOTE: not all metals show color change (manganese) and some people may not be able to see the color. If you don't see any color, ask a friend to look with you.
