Plant Bulbs

Plants need both red and blue spectrum.  The ladder being the most 
important.  Too much red and no blue spectrum will result in unhealthy 
plants and alot of unwanted algae.
On my 75 gallon I use 2 48" "Triton" (high Red)
and 2 48" "Coral Life 50/50" (high blue without the glowing purple tank)
