The mash was made using 4 Kg pale and 150 g crystal but pH was 5.8 after 10 minutes despite the gypsum. The water here is hard, I live on magnesian limestone, and in the past I would brew darker beers to achieve a better pH in the mash. I wonder if the gypsum doesn't readily dissolve because of the already high mineral content and just precipitates out? Then I wonder if there is already enough calcium in the water and maybe a drop of lactic acid would be a better course. What I do know is there is enough information on this site to answer my question but as my head is so full with reading that I'm totally mesmerised, I'll hopefully again take advantage of the great wealth of knowledge and assistance.
Our water company's figures are less than helpful, not even unit specified.

Can I ask, is there a simple answer or do I need to go the whole hog and get to grips with this subject at some stage soon?
