In regards to vodka dosing, in my tank the phosphate and nitate reducing effect was not permanent. Over time the levels began to climbagain and I was forced to look for other methods of removal. I have not read of this happening to anyone else so maybe it's just a fluke. I think the bacteria could not keep up with the nutrient input. As I increased the vodka dosage to compensate I did not observe a decrease in nitrates or phosphates. There must be some limiting factor that alows carbon dosage to work up to a certain point. Anyone else experience this? Anyway, I plan on trying lanthanum to control phosphates better with less expense.
