good point jonathan about aeration - forgot about that - they do aerate in line. perhaps, if he chills in the kettle (Immersion chiller) he could aerate prior to running off, although that would likely stir up the previously settled trub.
not sure on the headspace - 22gal for 20 wort would be close...
The fermenter is 23 gallons, i had figured this would be fairly under undersized for the size of the batch. But I should end up with a bit under 10 gallons with each, it's definitely going to be close. I don't have aeration set-up but I do pump in from the top of the fermenter, suspending the hose over the liquid. I know it's not ideal for getting enough O2 in to the batch. But this is what i have to work with right now.
Could you enlighten me a bit on your statement about starters not working well with dry yeast? I have no problem adjusting my process, just need looking for a little more insight.
And thank you both for the feedback.
