Benn kinda busy at work as of late. My tank parameters:
Chinese 212w LED
2:1 white:blues single fixture about 16" from water surface
I think the light may be too strong, I have noticed that my coraline algae won't grow on the tops of the rocks directly exposed to the light. The shadows and underside have grown maroon colored coraline.
All my corals except a couple colonies of zoa are currently located on the sand bed. I had a second fixture, but it is currently beoing replaced becasue it broke so all the coral is located on the "dark" side of the tank.
This is actually my second colony of yellow polyps I have lost, but like I said, the rest of the corals are doing great.
