It's quite common to see growths in developer rinses which are mildly
alkaline and contain organics or in finishing rinses like CU-56 but I've
not seen it in acid plating rinses. The best approach I've seen is to add
a strong hypochlorite bleach to the tank once a month to kill the
bacteria and then rinse thoroughly and refill.
