But with T5 over MH you will never get the best color from the corals and the display will still never look as natural as the shimmer effect you get from MH. T5s are better on energy and heat though, but a properly setup MH run off of electronic ballasts can also be energy and heat efficiant.
T5/MH combo is the ideal set-up.
Yeah I dont see ever going to T5. Once LEDs become affordable, reliable and actually deliver good PAR I'll probably go that route if heat and efficiency ever become an issue for me. T5 (or any flourescents) just dont do what MH and LEDs do for looks. MH coverage is a matter or how good the reflectors are and how many used. If you arent getting coverage, you need more MH or better reflectors, simple. I added up the wattage of other lights in the house (about 900 watts including 13 of which are only 13w each) and considered how much they are on between my wife, 5yr old and myself (not even including the TVs, 3 of 5 ceiling fans that run continously ect) and think its downright silly to consider the energy savings of 300w (MH) vs the 156w or 234w I'd be using with T5 on my 3ft tank and probably running longer. I haven't had a significant heat problem with MH yet (by that I mean I've never needed anything more than the fans the fixture came with or a few fans in the canopy when I used SE retro kit MH) though I'll conceed T5 has the advantage in most regards (its just the two it doesn't is looks and overall performance which can be better or worse depending on set up of either)
