Fun guys in the bath!
I have a boric/sulfuric anodize bath that has turned green. I am pretty sure it is fungus so I added Sodium Benzoate to the bath. I just seemed to get greener and now it is producing a bubbly foam. I have it tested once a week for H2SO4, Al, and H3BO3 levels and twice a week for Cu, Cl and Cr. It has all came out great. What can it be and what can I do?

A. Carbon filtration will fix you right up. I have used a portable set up with hoses, so that I could do the filtration on a batch basis as needed. It doesn't need it very often.

Q. Will the dead algae affect the bath or the anodizing process? Also, I've tried many filters but no luck on getting the bath clear again. It is staying a murky green color. Any suggestions?
