Thank you all!
So far after I had replaced the 2x fixture with a new 3x my java moss had exploded and the other plants are catching up. It could be due to the fact that the bulbs are new though, but I like the wider light spread over the tank and I think I'll keep the 3x.
Oh for the record:
Fish: Ameca Splendons; platys; pleco and some smaller fish in that tank.
Plants: java moss (pest, but hopefully will cover some babies), Anubias Bartery var Nana (old resident I used to and don't want to rid of), Coon tail, Duckweed (I guess), Vallisneria, Baby tears.
Substrate: flurite bed covered with gravel
