You just can't go wrong with T5 lighting

For a week now I've retrofitted 4x39w T5s I gutted from a fixture to supplement the 2 a360we over my 120g. Yea 3 would be ideal but with the addition of the T5 now I don't think I'll need a third. I've already noticed much better PE and the colors are returning on my sps. The purple stylo that never showed any PE no matter where I placed it is now perking back up. The red is coming back on the bubblegum digi and the green on the stalks of the forest fire digi. The hawkins enchinata is also starting to blue up too.

The shimmer and control-ability of LEDs with the spectrum and diffused lighting of T5 makes it a winning combo.

Just for curiosity were you only running the 2 kessil before? What percentage did you have them at before and after the T5?

Yes T5's are great bulbs for corals

Yes, just 2 and I have them on at 10 and ramp them up to 80 intensity til 4p and ramp down for the evening til off at 9. With the T5 I have them on at 11 and off at 8 to give the Kessils time to ramp up and down.

Thanks! IMO 2 360 not running 100% for the entire photperiod was not much light for a 120 so I think it was a good choice to add those t5! Figure the max the tank was getting was a peak of 144w (90w each running at 80% peak - less than that while ramping), adding 156W of T5 light was a smart choice! I think you would have seen improvements with adding that much more of any lighting type, but can't go wrong with t5.
