In my still very limited experience with a new 120 gal tank, three banks of PC
lights front-to-back on a 18" wide tank could be too much. This 120 was set
up about 15 days ago, has three PCs front-to-back, is 24" wide, and the amount
of light at the substrate level is staggering (I still have to measure it
though). Hygro won't grow up, it just hugs to the substrate, at a place
where the depth is about 20". Rotala indica shows pink growth at a depth
of about 15", and ambulia shows pinkish growth at a depth of about 8".
Yesterday I shut down one bank of lights and will keep it off until the
tank matures a bit. Under the same conditions, the same three banks of lights
over a 18" footprint would be definitely too much.
The light banks are dual 55 Watt AH Supply kits.
