I was not aware that the liquid methods removed much phosphate. I was under the impression pellets removed more.
I've stated this before.....regardless of the bacterial food source (biopellets, vodka, vinegar, etc) phosphates and nitrates will be "consumed" in a ratio of 1 to 16, respectively. This is biology....can't get away from it.....it is the way it is.....phosphates and nitrates are needed for life to happen. Please look up Redfield ratio to better understand what is going on with the "consumption" of the nitrates and phosphates.
