Id did think about that too @Slagter but want the sps too thrive and want all the corals colours to "pop".
You can keep SPS under T5's!! There are loads of really nice looking tank with T5's and a whole range of SPS corals!!

T5 draws less power
MH is cheaper but draws more power and runs a lot hotter
You can get very good results from T5's , especially in the "mid water" species of SPS.
But in nano's water quality could become an issue IMHO without a lot of effort
Thank you for all the info so far guys. Alot of pro's and con's to weigh up.
Watt for Watt they draw the same power
I disagree. Metal halides and T5's put out the same amount of heat Watt for Watt. It's just that the heat in a T5 is spread over the length of the tube giving the preception of a cooler light
Falcon have ever tested metal halide magnetic against a electronic ballast? I have and and there is big difference the electronic been far superior in every way.
