I live in Phoenix and my city water from the hose is always high in pH, TA, and CH so I went searching for a filter to put on my hose that would help reduce these. I ended up buying this one that is marketed for gardening and reducing calcium.

I tested my hose water before and after the filter and this is what I got:
Without Filter:
CH - 225
TA - 140
pH - 7.8
With Filter:
CH - 175
TA - 110
pH - 6.8
Whoa! I did not expect the difference in the pH. I doubled checked both with filter and without on the pH and it held true. Although it didn't lower calcium as much as I had hoped, it did appear to lower it. I am pleasantly surprised with the TA and pH being lower since my pool is always drifting to a higher pH.
I do not know how long this filter will last because it depends on the water being filtered and is rated for "6 months of gardening" which is highly subjective. I plan to test it every 4-6 weeks to see when numbers rise. Something to consider using, especially if you are doing some draining.
