Standard Lights for Red Sea 34 gal: From the Users Manual
"two 55 watt T5 power compact flourescent bulbs with a high-polish, textured aluminum reflector.... The lighting provides 1 watt per liter of clear blue sky color (10,000K) with a 1:1 ratio to pure actinic blue (420nm wavelength peak)".

as for skimmer removing nutrients I do use Coral Vite once a week when I have corals. Tried Coral Vite more frequently but no help.
