What's your incoming water pH?

[BowserB]

My pool water pH is constantly on the rise, it seems. I never have a problem of too low pH. That made me wonder what my incoming water is. Here is mine. Does this seem typical?
* Rain water (TS Imelda came through last night, so I had a good source) pH=6.9
* Fill water (softened with potassium water softener) pH=8.1
With our summer near-drought conditions and upper 90's daily high temps, I've mostly had fill water added with very little rain. Using about a gallon of 31.45% muriatic acid every five weeks or so.

Most tap water has pH between 6.5 and 8.5, but some municipal water suppliers may raise the pH of water as high as 9 to prevent plumbing corrosion.

Ours is 8 with a CH of 225 (much different than our well water when we lived in CT which was 7.4 and 50).

Interesting thread. My well water was 7.4 and CH of 150........good stuff!

8.2 for mine. I see a lot of acid in my future.

Imelda's remnants are pounding us right now! My fill water was at least ph 8 (that's the highest my test would go,) but my tap water CH is very low. I add a cup of acid every day. If I get a break in this dang rain I could use a quart of chlorine because I ran out yesterday and didn't get to raise my FC up before the deluge.
