Condition for anodizing by your self:

1. Use pure aluminum in order can get best result
2. Use pure sulfuric acid mean not contaminated by other chemicals
3. Use pure DC electric in order can get open pores of aluminum surface, for this you can take car battery, it’s depend on the current flow you need but better use current controller equipment in order can control constant current flow, current is no need too high but regular in continues flow.
4. Use anodized dying or chemicals coloring agent that already test in order get best coloring result. For this I have search in internet like Clariant also sell good product for anodized finishing. In your country could be different product.
