Finally got the pH down to 7.4. It took 3 quarts of acid to neuralize 2 boxes of borax. This is pretty much in line with the Proteam recommendation. I have turned on the spillover and will do more water testing late afternoon.

One thing I have noticed is that the water is so clear it actually seems to sparkle. I know this is just subjective but I really can't explain it any other way. Also, the feel of the water is 'silkier'. I suspect that this is because it is closer to the isoelectric point of the human body. I am starting with a salt water pool so to notice a subjective difference in feel is interesting. It actually leaves a 'soft' feeling on the skin when it drys. I guess this is the same effect of bathsalts which often contain borax.
