Rhonda I feel you would increase your likely hood of growing more difficult plants if you rotate 1 soft white one bath and kitchen , this will give you a little broader spectrum light output and a more pleasing colored tank . I have a 55G with a 4 - 40 watt tubes over it and have had cabomba , jungle val , and my dwarf tiger lotus bloom in it . Brad Bloomquist ivoryboxers at willmar_com
