Low to Medium-low Light 46" Bowfront
I am looking to do a low-tech (dirt bottom, no ferts, no CO2) 46gal bowfront planted (I haven't finalized, but mostly things lke anubias, java ferns, ludwigia, cypts, amazon sword, dwarf sag). My tank is 36" Long, 20" tall, and 12" wide at ends and 16" wide a midpoint.
I am worried the 36" Ray 2 will be too much light (I have a canopy and cannot raise the light more than maybe 2" without getting overly creative). Should I try two of the 18" Ray 2's? Or think about the Fugerays? Or do I just need to figure out a way to raise the fixture up more? Or am I missing something? I believe I need a PAR value of roughly 25 for this type of set up.
Another thought I just had, I will probably throw some duckweed in the tank. That should also filter some light, but I'm not sure how to factor that in, at least not in any precise kind of way.
