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.
