MH + T5

Just wait until we start talking about plasma!

I use T5 lighting and get excellent coral growth with both SPS and LPS. I will be adding LEDs as supplemental lighting to my tank just to get the shimmer and the extra pop that comes with the RB LEDs. I won't be going full LED anytime soon though. MH and T5 have the full spectrum of lighting down pat where it is too iffy for me with the LEDs. Great lighting to include with the MH and/or T5 but not for full coverage IMO. LPS and softie tank only... Then yes, full LEDs all the way. SPS... No dice.

MH+T5 for me.
Same reasons, color spectrum.

HOWEVER I am thinking of LEDs in the future for Heat, running cost and space reasons.
I've held off to let the spectrum issue catch up.
