esshup - Just for general information I would call the ethanol plant and see if you can buy 5 gallons. Tell they what it is for. They might even give you the name of a local supplier. They are in the alcohol business and should know.
sprkplug- you may be right. Just because something is frequently put down a drain and nothing appears to be harmed does not necessarily mean it is harmless. I will check on the MSDS for propylene glycol. They almost always have to list the toxicity for EPA approval. We should list for members the rubber and plastic parts that will be damaged in an aeration system is alcohol when put in the airline? I can't think of very many aeration parts that will be significantly damaged with a dose of alcohol.
