My kH is 9 - 10. And it does not come from a well, it comes from Hetch Hetchy. I'm keeping Tiger shrimp.
I can easily leave the water out over night and see what happens, however, my pH in the tank is still dropping to 6 after adding untreated (with pH buffer of any kind) from my typical pH.
I'll be sure to check out the other thread but any help would be really appreciated.
