I read all the cool stuff I was instructed to read I found it very interesting that everyday grocery items in place of high dollar pool store supplies. Ok enough of that! I took the advice to add borax to raise the PH the question is....if my PH was non-exisistant in the first place and I took the advice added a half box how long should it take to get any kind of reading on the PH. I know properly I would add slow wait 24 hours add more and hope I don't just get the reading off the chart. PLEASE ADVISE!
