letting tap water sit to lower KH/pH?
It was recommended to me by a forum member that letting my tap sit for 24-48 hrs might slightly lower my KH/pH? I have very hard water with a high pH.
Tested water from the tap: KH-19d, GH-8, pH-8.4 (before anyone asks its not a typo):/
I let water sit for 36 hrs and these were the results=KH-17d, GH-4, but the pH stayed the same! I've read mixed opinions online about letting water sit to alter things a bit. I was looking into a R/O unit but thought I'd come to the forum first for thoughts on this??
On a side note, any thoughts on other micro/macro nutrients being depleted because my water is so hard.?
