I am wanting to make my 20g a black water tank but am worried if my plants will will still grow due to lower lighting through the darker water
plants are
Telanthera Cardinalis
Crypt undulata
Echinodorus sword
anubis nana petite

Crypts, Anubis, and maybe enchinodorus (depending on the species) will likely be fine.
