Thanks for that George.
Which would you use to make magnesium water? The seltzer?
I'm struggling to make mag water at the moment with mag hydroxide powder - even if I pour a 1/4 bottle of the soda water or whatever off, add the powder slowly to it, and then remix (slowly) the 1/4 mag water back with the other 3/4 bottle, it still foams over quite a bit unless one goes real slow pouring in which case the CO2 gets lost resulting in a lot of mag hydroxide powder not being 'assimilated' and as such left lying in the bottle undissolved.
Was a lot easier with MoM but I don't like the flavours added to it as I can only get it here in the UK.
Hope you're running/ticking over well George!
