You might want to enlighten the forum first on what type of set up you are referring to, to include:
1. what type of substrate? 2. layers? 3. what type of plants and how many? 4.how much livestock? 5.what type of filtration? 6.CO2 yes, or no? 7. What type of CO2, DIY, or pressurized? 8. Water values? any other fertilization liquid, dry? 9. freqerncy of water changes.
Without any of this any advice would be hit and miss, and mostly useless.
Also almost forgot what type of lights are you using and how long are you running them, at what intensity. Without any of this information how should anyone know what could grow in your tank and what type of ferts it needs.
