Thanks for the reply. I am working with the 1.5 gallon kit. I have an aquariam airline ran in the tank. However I am considering adding another as I have another pump available. Is too much agitation ever an issue?

Also, does anyone know or can explain what the dark coating that forms on parts that have been dipped in acid is? Is this just the color of clean steel? If I polish then go to the acid I get the dark coating as well.

Also does anyone know what the problem with the chromate is?

Thanks alot, Ross
