Hi, I never got around to posting what happened with the pool and adding borax. Here's what I did - instead of getting a five gallon bucket of my pool water I got about a gallon in a large measuring cup, then used one cup of the pool water to experiment with. I started by adding one teaspoon of borax at a time then testing. I finally got the test to the correct level. I then calculated how much that would represent in the ratio of my pool water to borax. I added 6 more boxes of borax to the pool and my PH tested 7.6 finally!!!!! I used the smaller amount of pool water b/c I thought it would be a faster method than using the 5 gallon bucket. I appreciate everyone's comments and suggestions - after that problem I had practically a worry free summer!!!!
