i actually run a modified version of zeovit (Iwan's Method)
Every two weeks:
Prodibio - digest
Prodibio - optimum
Everyday
Zeostart 2
Zeo amino acids.
I can tell you that in my nano i have never been able to get my nitrates down to zero before running this modified zeo system. I used to have a fuge, carbon, & GFO. I was able to take all that equipment offline. Now with this method my corals are brighter in color, 0 nitrates and virtually algae free. i would recommend it.
