Carbon Treatment should be done according to your vendor recommendations.
Things to be aware of are:
Amount of organic leaching from dry film in pattern plating. If excessive
increase frequency of treatment.
Method of addition or replenisment of the additives. In a single component
additive system the rate of consumption of the different components may not
be directly proportional to the addition and C-Treatment takes you back to
baseline before things get too far out of wack.
Some additive systems are designed to minimize the need for C-treatment
especially ones where the different componenets are supplied and controlled
seperately. The frequency may be as long as once a year.
