Well I was in a hurry and ended up not adding anything other than Stabilizer 5.2. Being my 3rd AG brew, I'm finally dialing in my process. Everything went great, other than I broke my thermometer in the boil kettle while chilling.... it was only the outside housing and not the actually thermomter. Being a food thermomter there is no mercury or lead anyway... so my only concern is glass...
According to what I read, I'll be fine as long as I carefully rack to secondary, leaving any glass behind.
Hopefully I still get a great beer without the water changes!
