Upping trace dosage

I was reading through EI and found a 20 gallon example tank at 5.5 WPG dosing 15ml a week of trace. I have a 55 gallon at 4.7 WPG and had up to the point of seeing this example tank only been dosing 14ml a week of trace according to instructions on bottle. I use Flourish for trace. Is Flourish a good trace mix? I just recently bought a 5 liter container of TMG but there are no dosing suggestions on label. I intend to use up the rest of my Flourish stock and then switch over to TMG as I notice how fond of TMG many of you including Tom are of it. So based on the 20 gallon EI example tank I've upped my trace dosage to 30ml a week (4.3 ml x 7 days a week). Does this seem correct? After weekly partial I dose trace and 1/2 tsp KNO3 and then over the next six days dose a total of 1/4 tsp KH2PO4 and 1 tsp KNO3 along with daily trace and then it is partial time again. I have pressure CO2 with drop check indicator running borderline yellow with no mad fish. KNO3 consistently tests out about 10ppm and PO4 at about .5 - 1.0 ppm any day of the week including day of partial. Any obvious problems with this schedule? Your criticism is greatly appreciated. Thanks.

 

Thanks so much for your instruction Greg. You say that I should multiply the 20gallon example tanks dosing by 2.75. I presume this is because my 55 gallon is 2.75 times larger in capacity. I estimate approximately 10 gallons of my tanks volume is displaced by substrate and biomass. Should I take this into consideration when applying the example tank dosing to my tanks dosing? If so I would then need to adjust the example dosing by 2.25 correct? Should I make this increase in dosing all at once or incrementally over a few days time to give the plants time to adjust to higher uptake and avoid fueling an algae festival? Thanks again.
