When I was full time refining the flocculant I used for acidic solutions I got from an aluminum anodizing plant that I did a lot of contract work for - I never needed a lot of it for my refining work so they would just give me a small bottle of it when I needed it - I don't remember the particulars on it any more
Lou & Deano have both mentioned & recommended a company called Tramfloc for flocculants -----------

So you can contact them & explain your situation to them & they will likely recommend some of their different products & send you (likely free) "samples" for you to try to determine which product works best for you
Kurt, Thank You, I appreciate the information, I will run it down with the manufacturers. This was very helpful.
