If your PH is high like mine, you can use white vinegar to lower it. My PH out of the well is about 7.1. I use 4 lids of vinegar in 5 gallons water and that brings it down to 6.4 (sometimes a little lower)..i was stuck about the ph levels. i got a meter that will tell me how much its got and i now to keep it between 6.5 and 6.8 but how do i keep the ph levels under control i mean can i adjust them and how?
Not sure what to use for low PH...The PH "up or down" also do a good job; but my preference is to stay away from too many chemicals.
