Well that's a good place to start. I would still get your water tested. I have learned my lesson on that...

Just throwing this out there because nobody else mentioned it, do a calibration on your brewing thermometer, just in case.

After getting my BC my effiency went from 60% to 70% and after tightening it up my effiency is now at about 84%.

+1 for milling your own grain!

I'll double check my thermometer. Guess best way is to measure icewater to verify 32F and boiling water to verify 212? (I'm pretty much at sea level)

Definitely a +1 on the crush.

I increased my efficiency by 8% (72% to 80%) just by doing a finer crush.

The key is finding a crush which increases your efficiency but does not lead to a stuck sparge.

Cheers!

thats why I went with the MM3 vs MM2 mill...supposed to aid against stuck sparges....we'll see I suppose

most thermometers i've seen aren't accurate at boiling. Check it at freezing (ice water thouroughly mixed) and if you have other thermometers or a friend has one, check as many against each other at various temps, too.

icebath = 33.5 deg (hair off but not bad). IR thermometer I have reads 32.0F
hydrometer in cold tap water = 1.000

Hot tap water 112F, IR reads 111.5F

think thermometer is reasonably accurate

Don't use an ir thermometer on ' steaming' liquids. They also are very accurate only if they are calibrated to a certain material and you only check that material. The worst material is stainless steel, in which, they are worthless even if calibrated.

Copper on the other hand is perfect for an ir, but who has a copper mash tun? (homebrewer)
