4.8 WPG? That's an aweful lot of light. I have read a lot about people who had that much light and wound up reducing the amount of light because of tank stability issues. Algae growth, nutrient replenishment, CO2 useage, etc.
I wouldn't run that much wattage on one of my tanks. I have 3.8 and sometimes feel like it's a little too excessive.
Unfortunantly, the next lowest option is 2x55 which only puts you slightly above what you have now. If you could find a 2x65 kit, I think it might put you in a good sweet spot though.
