How to guess your waters Ca and Mg if all you know is its Hardness

If all you know with regard to your water is its total hardness, you can make an educated stab at determining its ppm Ca++ and Mg++ ion concentration as follows: First, convert whatever units your total hardness is reported in into units of ppm (mg/L) of total hardness "as CaCO3". Next, it appears a...

Re: Ro or tap

I discovered a problem in the metric version of 'Mash Made Easy' which led to fixes in both versions, and to the release of version 8.35. Changes made in version 8.35: 1) Fixes a problem in the Metric version with changing the percent concentration of Lactic Acid. 2) Fixes a problem in both versions...

Re: Ro or tap

A bit of trivia. I just determined that (specifically for the typical mash pH target range) 30% Phosphoric Acid and CRS/AMS should be essentially mEq/mL acid strength equivalents. Nigh on 1:1 equivalent in pH alteration and alkalinity reduction on a mL for mL basis.

Re: Ro or tap

That's true for the states, there are some very lively discussions on this forum about the US v UK approach. Also 1 or 2 mol acids, are less scary!! Some high Alkalinity UK waters would need a lot of Lactic acid to make a light beer! My well water has 377 mg/L alkalinity, and 459 mg/L Bicarbonate. ...

Re: Ro or tap

Some recent work I've done is indicating that a setting of 40% should be applied to Mash Made Easy's switch titled "%Log Base 10 Mash pH (Balance Linear)". The spreadsheet ships with this switch set to 100%, and 40% is likely to be found to be a better fit to measured mash pH data overall. And as to...

Re: Ro or tap

Ah-ha. I was getting to grips with DI_pH for base malts when I posted the MME snippet earlier: I'd changed the "base malt DI_pH" to Pilsner 'cos in the UK "Extra Pale Malt" is "Lager Malt"; there's no difference. But perhaps I should have increased the value to 5.75, 5.70, or even 5.65, to accommod...

Re: Ro or tap

For those wanting to make up a solution of calcium chloride in water: If you make up 100 grams of anhydrous CaCl2 (or 132.5 grams of the dihydrate form) to 1 Liter in distilled water, then its as easy as knowing that every 10 mL of your calcium chloride solution will deliver 1 gram of anhydrous CaCl...

Re: Ro or tap

Interesting MME spreadsheet, sadly no CRS or AMS or H2SO4 or HCl acid additions. That's in common with many water calculators. Those acids would all affect the critical sulphate and chloride balance, not just alkalinity MME has CRS/AMS. I agree that it has no accommodation for straight sulfuric or ...

Re: Ro or tap

As to base malt DI_pH (deionized mash pH, or the pH you will typically measure if you mash a grist of 100% of a single base malt in 100% deionized water with zero minerals added, or alternately in distilled water) compromise, there isn't much (if any) typically found difference in the DI_pH between ...

Re: Ro or tap

Excuse the repeat images in the last post: Trying to edit a picture posted in this forum is really pox! PeeBee, it seems that in Mash Made Easy you have forgotten to set the "Base Malt DI_pH Selector" drop down cell (lower right) to a compromise setting falling between your two base malts. Since th...

Re: Ro or tap

If you click on my 'Silver_Is_Money" username and search my profile you will see that I am the developer of a mash pH assistant software package. Mine is available via a free download, and my spreadsheet is both free and complete. It comes in a US units of measurement version and also in a completel...

Re: Ro or tap

Titration to pH 4.3 defines the true zero mg/L (ppm) point for the HCO3- bicarbonate species, … Thanks very much. A titration "end point" might have been what I was imagining, but I hadn't prepared myself for the explanation! :out That diagram. Remarkable I haven't seen anything like it before. Tak...

Re: Ro or tap

Here's one for "Silver_is_Money" perhaps? What is meant by "Alkalinity to pH 4.5"? I've an idea but sometimes my ideas depart with reality! <EDIT: Oh aye, and is "pH 4.5" a recognised standard for judging alkalinity? Thanks.> Titration to pH 4.3 defines the true zero mg/L (ppm) point for the HCO3- ...

Re: Ro or tap

TH = 71 = 2.5(Calcium ion) + 4.12(4.3)
Ca++ = 21.3 ppm

Back on page one I guessed at 33 ppm alkalinity, 19.6 ppm Calcium, and 5.1 ppm Magnesium. Not bad guesses in retrospect.
