just to reiterate what everyone else is saying.... crush and Mash temp.
I mash in with 162+ water (depending on grain bill) to get mash temps of 156F
You need to learn how to use some calculators... It really helps.
I use brewtarget which is a multi-paltform, open source program similar to beersmith. I set up my equipment, add my recipe, the mash wizard tells me how much water at what temp I need to to hit a certain mash temp.
There are other calculators out there. Use one. It take the guess work out.
