Hi Tony, it's been a while since you put up the Halides. How's everything doing and how are you liking it? I've started to debate going back to halides in my tank from the radion I have, so I've been looking through the old LED threads and this one came to mind.
My tank is nowhere near as big or as advanced as yours, but I just haven't been happy with the color the Radion puts out and was considering a 250w DE fixture with T5's to put over my 50g cube. And I've been going through a rough patch with my tank for the past few months, so I'm trying to isolate the whole chemistry/water parameters variable from the inadequate colors before I sell my Radion.
Just wondering what your experience and comparison has been thus far with the T5/LEDs and now the Halides.
