     I can already hear someone wanting to try PMDD asking "do you make a 
     300 ml solution or a 500 ml solution?"  Also, the "old" recommended 
     dosage was 3 ml/100 liters, or 1.1 ml/10 gallons, which resulted in a 
     3 ppm NO3 concentration for me.  Using the new formula (one tbsp KNO3 
     in a 300 ml solution), I should be dosing at 1 ml/100 liters to give 
     me the same NO3 concentration, but a 500 ml solution would require 
     1.67 ml/100 liters.  Yes, it's the same amount of KNO3, but tough for 
     someone starting out.
     The new recommended dosage of 1/12 ml/10 gallons (from a 500 ml 
     soultion, 1 tbsp KNO3) would be about 1/8 of the original dosage 
     recommendation, and would result in 0.4 ppm NO3 for me.  Shouldn't it 
     be 0.63 ml per 10 gallons, or 1.67 ml/100 liters?  I thought the 
     purpose of the new formula was to increase the macronutrients, not 
     decrease them.
     Is my math off?  Am I off?  I understand we each need to tailor PMDD 
     for our aquariums, but these new dosage recommendations seems to be 
     low.  Anybody else want to give it a shot?
