Floaters in AR? (Algae!)

[Brett Novak]

The best way to describe it is floating algae. These are 2nd run CERDIPS in AR after a 20 day AP soak. I've run this before but this is the 1st time with the floaters. Any ideas what they are? Maybe it's the excess peroxide forming a layer?

I'll capture and re-refine it anyway but just wondering if anyone else has seen this.

Guessing iron compound.

I've never used AP for cpus.

Gather the yellow powder and perform standard metal salt identification testing.
