Hi Woolsocks, I was just reading through a post on the forum where I had responded to you. It involved the mash /Lauter screens in your Specific Mechanical lauter tun. You were seeing your wort clarity fall to pieces about half way through the runoff. I'm wondering if you are still using the standpipe in you mashtun? We've moved to a piece of stainless mesh in ours that stands about 5 cm high. It works great and we get no loss in efficiency. Let me know. Thanks, Todd
