Trent, you were clear. No need to repost all of your comments. I take everyone’s advice here with a grain of salt. I assumed that one of the two brewing software tools would have got me to where I needed.
My thoughts exactly. You need to work to get a pH that low.

yeah I’ve never had something that low. And while I don’t know for sure, Martin and some readings suggest conversion would be pretty sub par at that low of mash PH, and yet he exceeded his target.
so i plugged that into basic recipe with RO water and ended up with target PH of about 5.2. while that is a metric crap ton of cacl and then the 2ml lactic acid, still should have been well north of 4.8ish.
Justin, did you enter your volumes, grist, and lovibonds into Brunwater correctly? What size final batch? I’m trying to get my head around using almost 15g of CaCl2. What profile did you use? Just curious.
yeah just adjusted all base malt recipe and 4.5 gal strike and 4.5 gal sprage. with those mineral additions and 2ml lactic, PH project around 5.10…super low. add any crystal in there and going to be lower.
Actually he would have gotten a very good conversion as his grain bill was a lot of oats and proteinase conversion is optimal with a lower pH (4.6-5.0).
So basically mostly Maris otter with some flaked outs. Bru’nwater seems right and likely about what he ended up with considering PH instrument margin of error.
