Works but,
Ok first off yes it works as advertised. But I have a 100 gallon system with well water that would needs like 400g to bring it down from a 7 to 5.5. If it came in more choices than 1 lbs and, I forget, 50 lbs I would for sure continue to use it. I hate paying to ship water. But it seems better for ro water, which I use but not in this system, or a small system like 20 gallons.
