FYI your LED light is very very lacking for a tank that size
especially with your 20K LEDs. (Im guessing you have non CREE royals)

and without optics, thats even less light towards the bottom of the the tank.

you have enough to keep softies, i wouldnt try to keep any demanding sps.


for sps, you should be looking at about 40 CREE XT Royal Blues and 20 Neutral Whites. and if the fixture is 8" from the surface, you want about 60 degree optics.
