i think i have the same set up as yours.
only difference is our lighting fixture. i am using t5HO lights (1 is plant bulb and the other is 10000k bulb)
plants that survived after 16 months are the valis, dwarf sag, amazon sword, some crypts and java moss.
here's a pic of my tank
how big are your discus?
good luck on your tank!
