What is the CH of your fill water? I was under the impression that AZ had very hard water. Unless your fill water is much lower in CH then partial drain is not going to do much good and you might have to lower TA again if you fill water has high TA. Realize that the lower the TA the higher the CH can be and still and the water is still 'balanced'.
If that is the case then don't wait on the borates. They make a big difference with a SWG in most cases for a relatively small expense.
