Now...this might bring up another question: How do I make sure the grain bed stays distributed?
Solution could be: the tube that enters the mash tun with the liquid being pumped from the HLT, is emerged in the liquid at set at a slow flow rate so that it wouldnt disturb the grain bed?
Is that a good idea?
