It is hard to tell from looking at the picture but whatever it is, it is too low. Keep working to get it up 7.2-7.8. (I like 7.4-7.6 best.) 6 lbs. of Borax isn't all that much in a big pool. What is your volume?

I have been estimating it at 30K - it has a 3.5 foot shallow end and an 8.5 foot deep end . . . I have 9 more lbs of Borax I can dump in . . .
Add a box at a time slowly into the skimmer while the pump is running. Keep the pump running and after about 2 hours, retest, redose. When the pH starts to move, you can decide if you need smaller additions to reach your target.
might be better to do the test outside with a white piece of paper behind it too...
Good idea, Philbo.
