Pretty sure someone can explain it better than me since I've never fully understood that either. But...

It all gets down to intensity. The T5HO may use fewer Watts, but they are more intense... I think the measurement of it is in "PAR". And the increased intensity also penetrates deeper into the tank. So for a given Wattage, the T5HO setup give more PAR at deeper levels, providing more photosynthetic energy to the corals. Same goes with Metal Halide... even more intense than T5HO.

Right on the money

Agree with kurt. T5 is usually a little better at penetrating water but it would be my guess that because you would have less wattage it would balance out to about equal. If you are going to upgrade i would save up for a 4 bulb or higher T5 fixture.

The coral looks fine to me expansion-wise as well. I have heard elegance corals do appreciate occasional feeding. Just don't over feed and foul your water.

about feeding the coral, i've been feeding it everyother day. i'll feed it some phytoplankton one day then next time some mysis...

about the T5 fixture there is a 24" 4 bulb 24w ea and a 24" 6 bulb 18w ea...i'm going to go with the 6 bulb because of the extra wattage.

the problem i have is i know i need a stronger light but since i have a corner tank i can't fit a larger lamp so im stuck with low wattage unless i go with metal hallide and i really can't afford that now nor anytime soon

thanks for clarifying my concern about lighting though

I'd skip the phytoplankton... that's not what it eats. Mysis and other meaty foods (chopped clams and the like) are OK though.
