I have been using the advice from Mr. Barr’s reply from below

1/4 teaspoon KNO3
~1/16" KH2PO4 or 2-3 drops of enema
On the off day, add 5mls of trace mix(TMG, Flourish or equivalent)
Do 50% weekly (or larger water changes)
So 4 days of macro dosing, 3 of trace dosing per week.
This is very heavy dosing and can be scaled back with less light, but it will not harm a lower light tank either.
Make sure you have good CO2.
That's the main issue with your tank.

I have a 55 gallon tank which is twice this size with bottled CO2 reading 30-35 ppm at the end of the photo period. There is 2.36 wpg and the tank is pretty full but not really with fast growers. I started doubling the above dose (because the tank size is doubled) but have since cut it back to the ¼ and 1/16 teaspoons respectfully. Using a LaMotte NO3 kit I notice that I am reading much higher than the 5-10 +- 1 as listed in the Estimative index. I do perform an approximate 50% water change weekly. I say 50% because I use a siphone drain not measured and I do not know the volume of substrate and driftwood but it is 50% on the glass. Should I change more water to re-set the tank more or lower yet the 4x per week dose amount to bring down the NO3 levels? It averages in the 17.6 ppm range from the LaMotte kit.
