JohnN said:One last update on this topic. I had enough water collected to do another TA and pH test, and these are the results:
TA 20
pH 7.0 or lower.
I think on my last test there was some Borax residue left in my pitcher, so that would explain the high readings.
On the last test, I was wondering if the rain was caught by run off from a roof or something. It seemed a little high on TA
(I would guess) as I honestly haven't ever tested rain water.
