if 720 applies then does that mean for a 3 mil coating at 12 ASF then tank time will be 180 mins.
Yes, running at 8ASF, I've had runs up to 240 and 270 minutes
by extreme agitation do mean mean like wildly boiling water??
Close but but by the time I got to that stage of anodizing, I had started to use a pump to circulate the electrolyte. It has a fast flow in the tank without the misting problems of aeration.
Here you can see my setups. I started using a pump on the 20 gal.

For your use of the parts, you'll have the most success by getting the tank temp down and improving circulation. By doing this, the pore size of the coating will be smaller and give a more durable coating. The parts will have a gold to golden brown hue to them and you should be able to use a 1.5 to 2 mil coating for the same end results.
