First brewday with the new RO system water, first time using Colorphast strips too. This ph stuff is driving me nuts.
My well water was tested at 216 Bicarbonate so the TDS of 16 on the RO was assumed mostly bicarbonate. I setup the batch for 8.5 gallons in EzWater.
10.3# pilsner malt
0.5# Vienna malt
4 grams gypsum
4 grams calcium chloride
3ml lactic acid %88
Does that seem ok for RO water? Ezwater said it looked good.
Anyways the ph strips said the starting water was at 5, i did 2 tests to confrim this. So I am thinking colorphast are off by at least 2 whole points? So I add the acid and now the strips are reading 4 (lowest possible reading on chart 4-7).
The water in my house was tested at Ward labs 2 samples at ph 7.7 and 8.1 (non filtered).
Can RO systems lower ph?
I threw a couple PH meters in the treated water (I don't trust them either) and they read 3.5
Should this mash turn out ok? will low ph denature emzymes? mashing at 148*F.
