Kickn,
I'll address the question you had early on that hasn't been answered.
The pink residue.
Aluminum sulfates, a byproduct of the anodization reaction on aluminum, normally deposit on the cathode. The color should be white or grey. This isn't generally a problem unless you let it build up, and it deceases the conductivity too much. Its easily wiped off of the cathodes if you get it before it hardens, The pink deposits indicate contamination. The electrolyte and the dye should be made with distilled water. Chlorinated water is trouble, the chlorine iron interferes with proper pore formation. You may be able to get away with tap water in the other operations, it depends on your water.
