Yeah, that's what I was wondering about, where people come up with their recommendations on drop numbers vs. tank volume. See, like 20 drops every 2 days sounds crazy to me, but only because I've only seen reccomendations for 1-3 drops. but your drops may be tiny little drops just allowed to naturally fall from the tip, where the 1 drop guy may squeeze his bottle a little and the 3 drop guy may not squeez his quite so hard. I hope you understand what I mean. Wouldn't it be better for me to find out the PO4 per ml. and then dose in ml's?
