Just to let ya'll know, the redo today of yesterdays parts turned out even lovelier than yesterday. Thanks again for getting me going, Larry

Greetings Larry,
Congrats on your progress.
As for adjusting Ph values I use Muriatic acid to lower the Ph
and Ammonia to raise the Ph values.
Using a plastic syringe (w/o needle) with a 3 gal Dye level,
it takes about 20 drops of either to increment the Ph value +-.1 with
a good stir after a "set" of drops before measuring, and
rinsing the electronic Ph tester bulb with De-Ion water b/t successive
measurements.
And don't forget to record the Ph value for your chosen dye on
each ano run.
As an example for my system; using Black dye I ran test batches
from 5.7, 6.2, 6.4, & 6.7. Another post of mine depicts the "blueness"
of the results for my system at Ph levels 6.2 and lower with a Ph at
6.4 resulting in an optimized color saturation in my opinion.
I have just begun my red dye optimization and I immediately set the
Ph value to 6.4, based on the opinions gleaned from archived posts
and my own intuition.
There are many excellent posts depicting the dye issue and I learned a
great deal from reviewing them. Black and Red dye results have been
keenly dissected by some knoweledgeable participants in this forum.
