I don't process mash water separately from sparge water - there is often no need to do this especially when you have effectively removed most of the alkalinity (by dilution with RO). So just draw the entire volume of water needed for both mash and sparge, add 1 tsp CaCl peer 5 gallons and proceed.

ok, just to clarify is it 1 tsp for the finished product of 5 gallon batch or 1 tsp per 5 gallons of water? for a 5 gallon batch i usually start with around 9 gallons of water, which would equal almost 2 tsp if this is the case. im assuming what your saying is i can just add 1 tsp to the HLT no matter how much water for a 5 gallon batch, correct?

No, it's 1 tsp for each 5 gallons of water treated. But bear in mind that it is a starting point guideline: not a hard and fast rule. If you want to use half a tsp or a tsp and a half per 5 gallons that's OK as long as you experiment with other values in subsequent brews to find the level that does the best for you.

brewing tomorrow and just want to clarify my measurements of calcium chloride based off the primer. 1 tsp per 5 gallons of water. 5 grams in each tsp = 1 gram per gallon of water. i will be using roughly 9 gallons of water, so 9 grams needed? i will be using 100% RO water.

It's more like 3.4 grams per level teaspoon (for CaCl) according to Palmer.

The exact amount does not matter. As AJ says, its not a hard and fast rule anyhow. The brewer would be advised to use a consistent unit of measure in his brewery (whether its grams, teaspoons, ounces, etc.) and make note of the changes made in the amount of salts used to satisfy his taste.

I'd much prefer that people work with weight but not every brewer owns a scale though he should an inexpensive student triple beam balances are still available though electronic scales are also now available at reasonable price. I've noticed that lots of brewers like to shoot and so a reloading scale, if you have one and can convert grains to grams is a possibility.

The weight per tsp is a pretty rough measurement and depends on the form (powder or prill) and, if powder, how 'fluffy'. 5 grams/tsp is fairly close for the prill form.

I agree it doesn't matter to an extent. Was just trying to help since my own measurements are fairly consistent with Palmer's table, so I tend to measure by weight and typically treat 15 gallons of water with 10g CaCl. It just conjured an image of a friend inadvertently overdoing the epsom and having an overly salty batch.

I'll amplify my answer and state that I prefer grams as that is also used in the 3 popular water chemistry models. Electronic digital scales are cheap and accurate enough for my brewery. You can check your scale by measuring the weight of a nickel coin - they are 5 grams.
