I've had better times with Java Fern, but that tank doesn't get any direct
sunlight.  My Anubias requires fertilization or it will eventually

I'd consider a floating bed of anacharis or duckweed, as well as H.
difformis.  I find that H. difformis can handle very low nutrient levels.
If your tank has an opens space above, you can also allow it to get its CO2
directly from the air instead of through the water.

Alternatively, you could place a potted philodendron beside your tank and
drape it over, allowing it to hang into the water.

I saw some nice tree philodendrons at the garden store recently.  Wondering
if one of those would pull nutrients out of the water.
