Hi Fellow brewers. Im about to start my first HERMS build. It will be a single tier. I need to buy a pump. Is there a march pump that is better than others, i see march pumps with different codes behind it, which one is best to buy. Also I allready own a 20 gallon blichmann brewpot, 15.5 gallon keg and a 13.2 gallon keg. I have a false floor for my brew pot so i was going to use it for the mash tun. I was thinking of converting the 13.2 gallon into a HLT and using the 15.5 gallon as a brew pot. Would this setup be the best way to do a HERMS? Im using gas for heat as well. Thanks for the advice in advance.
