Plantbrain...I have looked over your article before and found it to be a nice routine that I'm definately aiming for. The main thing is that on the example, the dosing regiment is listed as such for a 20g:
1/4 teaspoon of KNO3 3-4x a week (every other day)
1/16th-1/32nd teaspoon of KH2PO4 3-4x a week (every other day)
Traces added on off days as the macro nutrients, so 3x a week, 5mls each time.
SeaChem Equilibrium 1/8 teaspoon after water change.
Which leads me to three questions:
1. Is it okay for me to use Potassium Sulfate in place of the KH2PO4? Will it still yield a good amount of K and PO4? If so, would I still use 1/16-1/32tsp?
2. When you write traces, would that mean something like Flourish? Is it okay to dose that much when the bottle says 1-2mL 1-2x a week?
3. Does Equilibrium take care of Ca, Mg, and Fe? And if so, in reasonable amounts?
Thanks again for the help!
