AntiFreeze - How Much???

[OUBrew]

I have 160 gallon tank and I need to get it ready for a week break. We have been below zero every night for the past week. How much anti-freeze do I need to put in?

Well I think most boiler antifreeze is a 50/50 mix so you would need 80 gallons. That would be very expensive. I think I would have a neighbor or friend feed the fire while you are gone.

Yeah, if ya gotta drain 80 gal out to put in anti-freeze just drain completly and save money, or as stated get someone to fill for ya.
