Hi. I am having a problem with my ph always coming out low. I am very new to water adjustments. The only thing I am doing currently is Sodium Metabisulphite for chlorine and lactic acid to lower ph. I’ve got pretty good water so just starting small. I started both these changes at the same time and have only been doing this for about 5-8 batches. Never did anything for a hundred batches before (I know, I am ashamed lol). I am currently using Brew Father to calculate. I got my water tested so I know exactly what the numbers are and put them into BF. I use an InkBird ph meter. My problem is I always end up around 4.7 to 5 following their recommendation for lactic acid. Obviously I could always just use less than recommended but would like to not have to guess. Does the Sodium Metabisulphite change ph? Cause I did notice that the recommended lactic acid doesn’t change if I change the amount of SM in the recipe. Wondering if that is where it messes up. Any help would be appreciated.
For reference my water ph is 7.8 and depending on recipe it has me 2-4ml of acid to it every time.
