Default IIPA Water Adjustment

Here is my starting profile. I've been doing total replacement for light beers and I'm brewing an 13 gallon batch of IIPA with a SRM of 8.6. I would like to do a dilution to keep some minerals. How much would you dilute, or would you start with total RO and build?

pH 7.6
Total Dissolved Solids (TDS) Est 337
Electrical Conductivity, mmho/cm 0.56
Cations / Anions, me/L 5.7 / 5.6
ppm
Sodium, Na 31
Potassium, K 3
Calcium, Ca 61
Magnesium, Mg 15
Total Hardness, CaCO3 215
Nitrate, NO3-N 0.1 (SAFE)
Sulfate, SO4-S 25
Chloride, Cl 42
Carbonate, CO3 < 1
Bicarbonate, HCO3 169
Total Alkalinity, CaCO3 139

With a 75% dilution with distilled and adding Gypsum. Here is my finished water. Does this look like something that would fit the bill?
Would you add something or change dilution % Thanks I'm trying to get this water stuff.

Ca-51 Mg-10 Na-29 SO4-140 Cl-43 HCO3-49

I typically use "Bru'n water" program. It is extremely useful and pretty accurate as well. Not to mention it's free.

That tap water should be fine for a DIPA excepting that the alkalinity might need a little neutralization. A little acid will solve that problem. Bru'n Water will tell you how much.

I got it Martin. Thanks for the water software. IMHO it's the best out there. After a few more adjustments in the program it got me to the right ph numbers and sparge acid adjustments.

Thanks again
