How to treat Acid Zinc bath contaminated by dissolved Titanium baskets?

finishing.com is made possible by ...

Q. Hello
As the topic states, I have had some dissolving of a titanium basket in an acid zinc bath, solution is now murky from a white substance that gathered in the basket and dispersed into the solution while removing it. Anodes ran low and voltage high, I have since filled the basket.
Although it was plating with good results afterwards i cannot see my work in the tank clearly and would like to clean it up.
How should i treat the bath?

Thank You !

A. Hi Zach. A general principle in cases involving unknowns like this is you always try it in the lab on a small sample before attempting anything on the whole contents of the tank. So take a few ounces into the lab, pass it thru a piece filter paper, and tell us whether it solves the murkiness problem please.
Luck & Regards,
