Pro Products GP63N Poly Guard Corrosion Control and Sequestrant Crystal

This planner is good for those who still like to see things on paper at a glance. I like flipping through the planner to find dates in a second instead of fumbling through my phone. I keep mine right by my landline phone.

This product contains three pounds of crystals for almost the same price as individual 1.5 lb cartridges.Rather than throwing a spent cartridge away, empty, and then clean it (or put it in the dishwasher), and use a kitchen scale to refill with this product. This is enough material to refill a system twice, and a plastic cartridge can be used many times if it is opened carefully.

I want to return this item but amazon & seller didn’t process the return.👎
