Temporary Hardness and BIAB

[TonySan]

Having bought a Buffalo 40L and planning my first AG brew, after reading the forums I noted the principal of boiling the liquor and cooling to precipitate out temporary hardness, as I live in a hard water area.

However, if I'm then doing BIAB in the same boiler, does that effectively negate the process as I will not be emptying the contents, cleaning the boiler and then refilling.

I suppose the question is will the precipitate 're-dissolve' when the liquor is warmed to mash temperature. It's been a very long time since chemistry A Levels.

I have a buffalo 40l and used to BIAB and also suffer from hard water. You need to boil the water with a tsp of gypsum, preferably the night before for about 30 mins and leave to settle overnight and rack off into another vessel. I used FVs. All the precipitate can then be washed out and the boiled water put back in. I now use CRS as it is quicker and more convenient.

Thanks for the reply. The easy option sounds good to me !
