How high can I mix Instant Ocean before I have to worry about precipitation?

[Randy Holmes-Farley]

I still don't fully understand what's going on when you mix a multi salts and mineral mixed crystal with water until you get to what appears to be a saturated solution. Ie, a solution where you still have undissolved salts in the bottom.

Does each mineral and salt go into solution at it's own rate or is there an effect of the other salts/ minerals on the rate of mixing?

Each ion dissolves until it potentially precipitates with some other ion in solution, or it repreciptiates back as the material it started as.

In a salt mix, for example, calcium comes from calcium chloride dissolving and carbonate comes from sodium bicarbonate or sodium carbonate dissolving. Then the calciumand carboante combine and may precipitate. It doesn't much matter if there is any lithium chloride or other unrelated ion present or not.
