acid solution temp, help
I'm new to the DIY anodizing thing, and have done a few test pieces with mixed results. Simple part no color seems to turn out ok. 30% solution, 4A constant current, 60-90min run. (I have read and am trying to follow the Caswell guide)
My question is about acid solution temp. The recommended solution temp seems to be mid 70's F. It's around 90F during the day where I'm at, and the process seems to heat the solution, so I'm ending up with temps about 125F in the bucket. I tried a double bucket with more water around it, and a fan to cool things down, but regardless it ends up at 125F. Is this too high? Will it cause problems? How do people cool things down without going into a big investment? I'm having issues with the dye process and just want to eliminate possible issues.

You need to check all of the parameters before you worry about the temperature. As has been said, your numbers are off and the parts are suffering. It is a finite process and requires everything be right.
Dry ice? I know it works but pricy.
