Air in anodize bath

[jime]

Introduced an airstone to agitate my annodize bath. It improved the final product, but started disintegrating after being inthe bath for a couple of hours. Anything work better? I can use compressed air or an aquarium pump.

Either of those will work fine.

Jime:
I would steer away from the air compressor unless its a diaphram type.
If it is the piston type it will introduce tiny amounts of oil from the crankcase into your bath via the air hose. That will cause nothing but problems.
The aquarium pump will work great.
