Don,

                I had this problem before. (Sounds like you have a good
        DI system) We had to make a portable vacuum/scrub/filtration system
        that we would weekly sweep/mop/scrub the rinse tanks to remove
        this beast. I couldn't find a way chemically to do this (but I
        also didn't have Technet's exposure either). The good thing was
        that the portable vacuum could also be used to capture any 
        fiberglass and metal particulate that accumulated at the bottom 
        of the tank.

        Groovy

     Has anyone had any exposure to fungal growths in thier plating line 
     rinse tanks (especially after the acid cleaner).  This hyphae is quite 
     hearty and nothing seems to kill it.  It is not an algae.  I've even 
     tried glutaraldehyde, a common antifoulant used in the metal finishing 
     industry, to no avail.  What does anybody say?
