## Description

Product Description Nature2 W28125 Replacement Mineral Cartridge, for G25 Pool Sanitizers From the Manufacturer The Nature2 replacement cartridge for 25K Gallons Nature2 G25 pool sanitizers destroys bacteria and controls algae using natural minerals, reducing potential for stinging eyes, skin irritation, and unpleasant odors and helps stabilize pH levels.

Review: We built our pool 5 years ago, and installed this "extra" filter during construction. We replace the cartridge every spring, and our pool maintenance is easy. We also like the fact that we can keep our chlorine at 1/2 the normal level (0.5 ppm) and still maintain clear, clean pool water. Our pool water feels like bath water, no chlorine smell or itchy skin. This filter costs $130 in local pool stores, so this price online is VERY reasonable! And it saves us money in the long run because we purchase less chlorine.
Review: I have used this product for over 20 years which provides automatic chemical feeding in my pool. Allows for less time in me adding chemicals. This I not a replacement for regular chemical adding, but does allow for reduced need to monitor and add. Great product and best price on desertcart. I recommend.
