These liquid percentages seem really overloaded.  May vary slightly,  10 grams per 250 ml == 40 grams per liter.

at 40 grams per liter, i was getting somethign that looked vaguely like urine, and wasnt growing anything.

I dilute that now . 25cc "LC concentrate" to 975cc de ionized water, and that seems to be workign considerably better.
