Rated 2 out of 5 by Kaylagirl Doesn't do all that's promised
I live in Arizona and our water is pretty hard. I was hoping to use this to get rid of the hardness (GH) and this product got rid of some, not a whole lot, but some of the hardness. If you're looking to significantly impact the GH of the water, this product isn't for you. If you're looking to lessen the GH by the tiniest amount then I'd say go for it.

Rated 5 out of 5 by Melian Works like a charm
I've only ever used this stuff and have never had issues. It lasts forever, too.

Rated 5 out of 5 by Gclo2 The best out there!
This stuff is the best out there and even the smallest pack treats 1,888 us gallons! This will last like 4 years and is very cheap.
