I am really planning on making this my grow out tank for coral then moving them into my 125g. As far as lighting it is an led fixture by Beamworks not sure of the quality of the brand but the corals sure do love it. I had a colony of zoas in my 125 with coralife t5 and they were doing OK, I moved them into this one and they have almost doubled in size already. What amazes me about this tank is that he had it setup for a year, started out with frags and it looks like this only using an oversized skimmer and two power heads connected to foam filters for filtration.
