Frag tank lighting

[fener103]

Getting ready to change the bulbs in my coralife unit and need to get 2 new bulbs for the 150's what K rating are you using and more importantly why? Thanks!

I'd try the radium 20k or phoenix 14k

It depends on what you want, Ive got a 20k ushio over mine becuase I wanted to check out the spectrum before buying any for my display but I'm definitely noticing less growth than I had with the Phoenix 14K I had over it previously. Granted Ive got DE lights so I'm a little more limited in my bulb selections too.

We run a ushio 10k over ours. Colors not that great but everything grows really well.
