I'd get a fiji purple in there. For my 4 bulb I was going to go 1 blue plus, 1 aqua blue special, 1 coral plus, 1 fiji purple. I threw the coral plus in there because it had just come out and wanted to give it a shot.
Now I have an upgraded tank, now 55, and am looking for a new lighting unit. It is either a 6 bulb or led
. I was looking at the 6 bulb T5Ho from Aquaticlife since it had a built in timer and only 1 cord. And for LED
, I was thinking about 2 Orphek LED
units. Couldn't find a link to the aquaticlife ones, but you could just look at thier home page for it. Here is the one for the LEDs. Hope this helps.
