Okay. I will add polyquat, then begin dosing with bleach and bringing the ph up (it's in the 6.5/6.8 range) before I add salt and turn on the salt system. I did seem that adding salt raised the ph before, but that was with the other well water. BTW 5 days in the bucket tests for both wells show the small well water still clear and the big well water still brown with splotches of brown beginning to coagulate along the sides of the bucket and on the bottom.
