I brewed an Octoberfest Ale this past weekend....used two different strains of yeast that I had leftover from previous batches that I made a starter with. The starter I made seemed to do okay, not great action but I thought it would be enough to get things going and grow from there. I started bubbling away about 6hrs after pitching. It never really did bubble that great though and only bubbled for about 2 days, if that. So I tried to aerate the wort a little to see if that would do anything.....did nothing...There was very minimal krausen as well....so I took a gravity reading. My starting OG was right about 1.54, when I took the reading 2 days ago it was about 1.26. I thought maybe try racking it off the yeast and back on to get it going again. There was very little slurry at the bottom as well. So yesterday I went and got a new vial of liquid yeast and pitched that. I still have no action.....and now my 2 piece airlock is not even moving, which it did before.....so what the heck is up with this? HELP!!!!
