does one have to worry about oxygenation (sp?) during the lautering stage of all grain? i assume no, because you still have to do the boil. i'm reading "How To Brew" at the moment, and i am thinking about my wet-dry filter for my fish tank, and its sprinkler system. i'm guessing a sprinkler type system, or a "spray" type system would be more apt to mixing the wort then just a simple drain line back into the MLT. am i wrong? would it foam too much? is it a waste of time?
second question, and its hard for me to explain. while adding the sparge water to the MLT, i should be letting some of the wort out into the brew kettle. so it seems to me that i would have to get my flow rates pretty damn good and close together if i were to use some 3/8" ball valves to controll it. from what i read, we want to keep about an inch of water over the grains to keep them from getting stuck. so if i crack my ball valves wide open, it should only take a few mins for the sparge water to drain out of the HLT and the MLT, into the BK. is this long enough for a good extraction? is this what all the AG guys do with their brews?
