I was thinking of adding an LED strip like the ReefBrite, but it's a small tank and I'd prefer to keep the look clean.
Was also thinking of getting the Kessil narrow reflector. That will concentrate the light and up the PAR for the acros, but it might make the shadowing worse.
It won’t look clean if the light you buy has light spill all over. Keep that in mind. First thing I thought of when you said pico and G6.
