i use the Randy's 2 part recipe.  There is no need to mix any of the solutions again.  Once it is dissolved, it wont percipitate out.  I don't know about the commercial mixes, seems like a waste of money when you compare costs to getting the chemicals from chem master or bulkreef and mixing your own.
