Sorry for the losses 
It does say there's vinegar in there, so I bet it's just a diy carbon dose, the aspartic acid is the excess nitrate, and you're introducing bacteria as well. But I don't think I would dose a carbon source a couple times a week. You're just introducing bacteria, their food source, and then the remainder of the week the bacteria die?
