Absolutely. Being homebrewers we can decide on what is our own best practice, based on our own requirements which are perhaps more aligned to smaller quality batches and less on volume & cost.

No you can't, best practice is best practice by definition.
Cambridge Dictionary.
best practice - noun
a working method or set of working methods that is officially accepted as being the best to use in a particular business or industry, usually described formally and in detail:
Merriam-Webster
Best Practice - Noun
Plural-best practices
: a procedure that has been shown by research and experience to produce optimal results and that is established or proposed as a standard suitable for widespread adoption

Or make your own CaCl2 solution, whilst you are supposed to use distilled water, I wonder having very low mineral water if I could sucesfully use that if I first remove the chlorine by boiling?

Or (and I think I've already mentioned it): You can measure the concentration of the finished solution with a hydrometer. But if you want to prepare really strong solutions (e.g. 33%) you could use a "Pyknometer" ...
I did my first brews using a solution with one I prepared myself (7.4%) using a brewing hydrometer, and you should be good to about 10% with one. All the tables I could find were American (it's used for deicing roads, etc. over there) so used a 60F calibrated hydrometer (easy conversion, but possibly not important).

I am just about to make a 33% solution, daft question though, how many mls of 33% solution required to replicate 1 gram of CaCl2, or maybe a weaker solution would make measuring out easier?
My flaked is 77% by the way and I do wonder now what purity the brewing water calculators assume

I don't need to be irate to deconstruct your lame arguments. It's nice that you've seen a humorous little quip that you can lift from a recent thread. Well done you, i'm glad your are now feeling all warm and fuzzy.

@Galena: Right, you've forced me to take a look at that link so I avoid contradicting anyone. I got 6 minutes in, and that lady doing the youtube vid starts contradicting herself!
Anyway, she latterly said 33g (plus a bit because she's using a 94% solid ... we'd probably call that "anhydrous"!) made up to (i.e. not in) 100ml. That's what I would have assumed too. Therefore, 3ml will contain 1g. Well not exactly, you'd want a 33.3333 ... etc.% solution for that. You can do the maths; it's making me head hurt. 1ml contains 0.33g, 3ml contains 0.99g, etc. Get it?
You said your water calculator supports liquids? Plug 33% in and it'll tell you (I hope!). A bit of "reverse iteration" might be necessary (you've no idea what "reverse iteration" is? ... Damn, I've just made the phrase up, but I thought it might be right?).
Anyway, the solutions you can buy are usually given a tolerance of ±1% (i.e. my last 1L bottle tested with a
pyknometer came out as a 32.2% solution, but I haven't tested the current bottle 'cos I'll be told not to be such a dozy so-an'-so.

I quite liked it, thought it was ideal.I don't need to be irate to deconstruct your lame arguments. It's nice that you've seen a humorous little quip that you can lift from a recent thread. Well done you, i'm glad your are now feeling all warm and fuzzy.

Indeed, but you get the gist of it.
I do now yes :)
Well, it has the option to change to liquid and set the % in the settings, but oddly it does seem to make any difference in the water additions, it remains in grams and the number remains the same, so I am assuming that it does not work unless I have missed something.

Having seen the video now I know she was talking about the damage chlorine can do to rennet. It's a cheese thing so no worry preparing the solution for beer brewing.
I've used the CaCl2 solution to try and make mozzarella for pizza. Damned if I could make it work, so went back to unhomogenised Jersey milk from Tesco. Since found a local supplier of unhomogenised ordinary cow milk. Anyway, digression over.

Sounds very much like the authors have been applying "reverse iteration" to their heads?... so I am assuming that it does not work unless I have missed something.
