Actually the difference you're seeing is because Flourite has _no_ 
affect on pH. Most other gravels have a slight tendency to raise 
pH... So in the tank with Flourite you see the full effect of the 
buffer you're using and the normal acids produced in an aquarium... 
but no contribution by Flourite, either up or down...whereas in the 
other tank you see those effects in conjunction with a slight pH 
raising ability of the other gravel. BTW, which pH do you want?
