Lighting question. Single radium 250 vs dual 150w

illjoshlli · 05/27/2012, 01:38 PM

Currently I have a 58g 36x21h19d tank and I run a single 250w 20k with a nice reflector and two stunner strips. It's a mixed reef but a large amount of sps. I'm looking to either upgrade my bulb to a 250 radium ran on overdrive... or switch to a dual 150w with t5s.. I'm guessing the 250 gets me more par at depth but the 150s would probobly give me better spread..

What does everyone recomend? It would be much cheeper to just upgrade the bulb from what I have... but I like the idea if better spread. Currently I get a little shadding in the tank having 1 bulb in the middle

Do you have a radium right now?

What ballast are you using?

I don't, but I'm do for a replacement. I believe I have the lumatek adjustable 250w+

I would go with the radium and turn it to the HQI setting.

I would go with the more even spread. You can always move coral up higher if needs be.

What reflector is it? I have run both dual 150's a single 150 and a single 250 over a 58 numerous times.
