We recently installed our Fleck 7000 1.5cf Calcite Corosex blend Neutralizer. Within 12 hrs, no more pretty blue/green water in my sinks, or my hair! Best of all, no more white rings from acidic water, on my black trucks.
Simple to install, maintenance free. My neighbor told me about it, now I've told my other neighbor, and now they're ordering from CWS! Amazing product, fast shipping, and the customer service can't be beaten! Love it!
