The Rainshower GRDGROW-MP-RS Garden Grow Garden Dechlorinator is the best way to ensure your garden's ecosystem stays healthy and thriving. The Garden Grow filter uses 2 lbs of KDF-55 to effectively remove over 85% of the chlorine from garden hose water, and 2 ounces of energized crystal to reduce water cluster size. It will process a total of 20,000 gallons of water or more. As commercial nurseries and organic farmers alike will tell you, the soil is alive with microorganisms that maintain the fertility and disease resistance of your garden's ecosystem. That ecosystem is threatened by the use of toxic chlorine disinfection, because chlorine cannot tell the difference between harmful pathogenic bacteria and beneficial bacteria in your garden's soil. The GRDGROW-MP-RS promotes healthy plant nutrition by returning the natural balance to your soil, compost, or mulch. It will also enhance the effectiveness of non-chemical pest control methods. The Rainshowerr Garden Grow filter system features a replaceable cartridge filter, as well as a shock-absorbing design to prevent hose wear. It is made in the USA by American craftsmen.
