My effic. just plain sucks.....no matter what I do it seems as though I cannot get about 60-63%. I am using the Igloo 60 qt cooler with that little ridge in it with the wheels, then a SS braided hose for my filter. I stir at my mashin for a couple of mins, let rest for an hour, then batch sparge and once I have added my sparge water I stir another couple of mins and let rest for about 10-15 mins and then let her flow out. What can I do to improve this or am I doing something wrong here? HELP!!!! A man brewer in need of some serious help with serious issues.....
