Anodized aluminium is fine to use in a loop if you can GUARANTEE that the quality of anodizing is perfect. The slightest scratch that goes thru the anodized layer, exposing bare aluminium underneath, will result in corrosion taking place very quickly. FluidXP etc will slow down the problem, but if you don't change the FluidXP frequently enough then corrosion will still take place. Same applies to distilled water and anti-corrosive additive.
As you can't guarantee the quality of the anodizing in the hardware within our scene, it's just safer to steer clear of aluminium altogether.
