are you gonna continue to use that light to grow out the frags? How do the corals like it?
Even though the rocks were starting to color up by November, I was concerned that it might not be enough light. So I decided to add some T5s and reflectors that I had laying around. I had to construct a way to mount them which you'll see in the pics below.
A few weeks before implementing the light upgrade. ( November 20, 2015 )
The black material is called Centra. It is a foamed PVC and is light in weight but more flexible than I would like for this application. To increase rigidity I doubled the thickness by adding an extra strip to each side. From past experience, I've found the skin on the surface of Centra does not glue well, so I attached the strips with screws.
