My well has gotten worse since last summer...
From memory, and very close: Yes, 25 ml tests, always...except FC
Yesterday: Ran them twice to be certain...
I have two sources to check out yet, but I'm not sure I can improve a whole lot on this for my fill even trucking in one of those sources. If I can get either, and one is better, it probably wont be by more than 500 CH and 160 TA. I do plan on some makeup from my softener, but it's only good for 400 gallons a whack. I'll be using a little acid no doubt.
