I can't wait to see the result.

Plants and bacteria will mineralize N pretty quick and the 6 month time frame is about right to see plant plant differences.

NO3 of this tank has been 0 (API and Seachem) in the past 8 weeks! Contrast to other non-CO2 tanks with high fishload, I cannot explain why my NO3 went down to 0?
And here's an update of the tank. The plants grew like weeds in past 2 weeks, while the water temperature raised from 23 C to 25 C.
