When you do dead sea, the precipitate gets really thick, like oatmeal
consistency. So do it in a large enough container and leave some room 'cause you'll
most likely end up adding more water as you go in order to keep the consistency
thin enough.
The simplest way is to take your filter dead sea water, bring pH up to 10.78,
then drop it with HCl or vinegar to 9 and that will place the magnesium back into
solution and leave you with gold m-state.
8.5 is really the product with least magnesium, but in that last .5 pH you
will also lose a quantity of gold with the magnesium, so it's best to stop at 9.
Wash 3 times to eliminate salt and you're ready to go.
Dried is more powerful than wet.
