Tanot where do people get food grade Epsom Salts from?
Most supermarkets store pharmaceutical-grade salts - meant for baths, but they should be pure enough for consumption (especially since MgSO4 is still used as a laxative, which is a pharmaceutical use). If you want something that is specifically marked (and marketed) as ‘food grade’, this is what I bought.
Tanot I presume I’d be missing something if I go with no hardness at all?
If you polled this, you’d get at least two opinions per person… I personally prefer having a bit of magnesium (or calcium), but a lot of people go with bicarbonate or even pure de-ionised. Try different combinations, and see what you like.
Tanot I liked the Minima based mainly on Dave’s reviews and videos but it seems like they are problematic to get hold of now.
Order direct from ACS. Not problematic at all; what may be more problematic is that the warranty is going to be parts-only, but they are well built, and have been in production for quite a while, so not likely to go wrong soon after purchase.
