Currently, I am running 250 Radium with 6 x 24W T5s.
I like that combo and there is nothing wrong with it.
But I have been running the same set-up for a while and looking to do something new.
I can't add any more frags since I have no more space. Tank upgrade is out of question.

Only thing I can think of is to change out the lights.

I'm thinking about swapping put the T5s with maybe 2x15 watt Radions with 250MH?
My tank dimension: 36.5" x 24.5" x 25"

Any input?
