Just add it to the AS and shake it up. I wait a bit and then shake it again. One word of caution: go slowly in adding the crystals. You can always add more but if you put in too much it will not be a pleasant experience.
Yep add one at a time and leave for a day before deciding if you need to add more. 4 crystals seems to be about right for me per 100mls YMMV of course.
If you melt the crystals in glycerin, just enough to cover them, you can add a drop at a time and shake it up. You will know instantly if you need to add more. It is hard to go to strong when adding a drop or two at a time.
