The benefits of living on sand. My water is only 30 feet down too.Wow. You've got nearly RO water there coming out of your tap! I'm jealous!
I would go higher on all your numbers here. You should try and at least hit the minimums recommended (CA at least 50, Mg at least 10) in the spreadsheet and for an IPA I would try and target Moser's ideal pale ale which is higher around all over. While your Cl:S04 ratio may be ok (I'd probably go even more to the bitter side) the amounts of Cl and S04 also matter. They're too low if you ask me. Look at Moser's numbers. Target that.

So for an extract, in my situation, you would still shoot for salt quantities in a water profile? The SRM parts wouldn't matter though, correct?
