93 cube, 15 cube, roughly 15 gallons in 1st sump and 8 in second sump plus 12' of 1" pvc and 12' of 3/4"
@dantimdad - for the 92 cube, If I were you, I would take out a little less than a gallon per day if you're running the #DOS! If 1 gallon a day equals 3785.41mls, I would start trying around 3100mls per day and see how that goes for you or try less!!
