RO water system help! How much water can I get a day?

ok question it says this "Baseline: Add 1 tsp of calcium chloride dihydrate (what your LHBS sells) to each 5 gallons of water treated. Add 2% sauermalz to the grist."

First sauermalz? I assume this is a grain of some sort? The grist? Is that my grain bill? So if it's 56lbs so I'd add 1.12 lbs of the sauermalz?

Now the recipe guide I found online for an amber beer is 1 tsp of gypsum, 1 tsp calcium chloride and 3/4 tsp baking soda. This is from beerandwinejournal.com

I donated to brunwater and am water to get the email from them.

1 tsp of calcium chloride dihydrate to each 5 gallons? Assuming that's CACL2, I typically add 5 grams to 5 gallons. I don't know how many grams is a teaspoon (level? heaping? I hate volume measures like that), but it seems very high for 5 gallons to me.

[And when I say "typically" what I mean is that it depends on the recipe, but I follow what the spreadsheet says to add.]

Sauermalz is acidified grain. In other words, a way to add acid. I personally add lactic acid. Sauermalz was developed so brewers following the Reinheitsgetbot, the German Beer Purity law, could adjust pH.

I assume the other recommendation for water additions is for a 1 bbl batch? Otherwise seems very high to me.

I'm making a red ale and a nut brown I have another water recipe for the brown.

I rarely make lager since it's my least favorite.

Although that may be the case for drinking water RO's (meaning something super slow, like 12 gpd), anything over about 20 feet of 1/4" tube and you'll start losing pressure, noticeably when dealing with something like a 75 gpd membrane. We ran the tests in-house years ago...

Just saw this play out again when we did some maintenance on a residential scale system with a 100 gpd membrane at a customer's facility (the Cincinnati Zoo). 1/4" feedwater tube was about 20 feet long, and gauge pressure was about 35 psi. We replaced the 1/4" tube with 3/8" tube and the higher flow resulted in 50 psi at the membrane.
