RO it is then. I am still confused on what treating the whole batch of water at once means. Treat the mash water with enough for the preboil 6 gallons?

A teaspoonful of calcium chloride or gypsum is 3.5 -5 grams depending on how 'level' and how fluffy the powder is. It's an approximate measurement.

Thanks AJ, that’s what I needed. Palmer said it was 3.4g for the CaCl2 and 4.0 for the gypsum with a level teaspoon. I have adjustable measuring spoons that use a slider to reduce their volume. I can measure small volumes quite accurately, but can only weigh within a gram or so.

Wobbegong you’re fine. I was sloppy, I should have been more precise. Feel free to jump my butt as needed.

Gjabball, the whole batch is mash water + sparge water. If you’re using RO you can put it all in the mash or do the mash and the sparge together. Either way is fine, just don’t sparge with highly alkaline water.

So if I put it all in the mash lets say 4 gallons of water (with grain) and get a PH of 5.3 won't my PH in my brew pot be off if I sparge with RO water and my final preboil volume is 6 gallons?

No. Your mash pH will be where you want it, if you follow the water primer instructions.

It's often easier to just put all your water in one place (if you have an HLT) and just add the calcium chloride and/or gypsum right to all the water.

Oh I understand. I am using coolers ( until I upgrade in a couple months) and my brew pot is only 8 gallons so I can't fit all the water in the pot. Can I divide it up?

Sure. Just add the salts to your mash and sparge with RO water then, to make it easier.

So add all the salts to my mash and sparge with RO water. After that my preboil should be fine without adding anything else?

Yes, assuming your additions follow the basic "primer" guidelines and don't go overboard of course!
