Okay, I converted 4000mg and am unsure as to the concentration and final ml content. I used all oil (A says 41ml of oil) and all the 4000mg of pellets. I am thinking I should have 50ml or so with 75mg/ml? I guess 41ml of oil + 4ml from the pellets (he says in his instructions) + 10ml of magic solution = 55ml total. HOWEVER, he doesn't subtract the white bottom layer (filler?), or the dark brown one (though I still have that left in mine). So, whatcha think? 55ml at 72mg/ml or maybe closer to 50ml at 75mg/ml? Any and all help appreciated of course.
