This is what Tom quotes as daily estimates of nutrient uptake in his article:

"Some Typical uptake rates at high light and CO2 levels per day (24 hours):



NO31-4ppmNH4
0.1-0.6ppm(do not dose NH4!It will cause algae)PO40.2-0.6ppm

These rates do not assume that you will show deficiencies if you dose less than this, but adding more than these rates will not help further plant health."

Easy enough

Now this is what Edward states his PPS-Pro system adds daily into a planted tank:

"I basically got what Edward says that each dose adds.

This is what I got: - - - - - - - - - - - - - - - -Edward says:
NO3 is dosed at 1.05 ppm per day - - - - - - - NO3 is dosed at 1.00 ppm per day
K is dosed at 1.41 ppm per day - - - - - - - - -K is dosed at 1.33 ppm per day
PO4 is dosed at 0.11 ppm per day - - - - - - - PO4 is dosed at 0.10 ppm per day
Mg is dosed at 0.11 ppm per day- - - - - - -"


So what am i missing out on here guys?
I always thought black is black and white is white.

If as Tom says adding more than the recommended daily levels of ferts will not help with any additional plant growth in a high light/CO2 environment then where lies his criticism of PPS-Pro?

It does not make sense to me.
