Please help me understand my water test results

[bmcwood]

I got my results back from Ward Lab and I don't really know how to interpret them. I want to add gypsum to my apa's / ipa's but I am not sure how much with these results. Anything else I should be adding? Thanks!

Try downloading EZ WaterCalculator or Brun' Water there's a ton of information on their site. I was once in your shoes and elected to use distilled or reverse osmosis water and then add in the minerals and salts needed. If your water source is consistent year round and year after year then it's a good idea to learn how to tweak it instead.
