A little while ago I decided to try adding to my lighting. I've had the idea floating around for a few years and finally decided to give it a try. I picked up a used 4' T5/led hybrid fixture in excellent shape. I'm still using the kessils down the middle, in between the 2 T5 fixtures. It added light to the front and back of the tank, obviously, but it also added a lot of light to the ends of the tank, which is what I was after. Lights in the old fixture were only about 2 feet apart so the ends were really dark. Right now I'm dealing with the gunk that goes along with light hitting new parts of the rock. Not enjoying this stage but I know it'll clear up eventually and now I have space for more coral!
Here are some pictures with the top down viewer:
This setosa has a strange growth pattern. I assume it's due to the coral growing on the side of it. I've tried to frag it off but it came back.
