Is that a 150w Metal Halide fixture? Corals can requorte form 3wpg to 6or more wpg
, but wpg
is a very generalized rule. It's really PAR that corals need for growth. You should be able to place corals with lower light requirements at the bottom and move up along with the light requirement of each type of coral. Research not just the light level but the water flow and feeding requirements (most need only light, some require being fed).
If you got uncured LR
, put it now to help cycle the tank. If you are getting fully cycled LR
from a LFS
, then you may want to wait till the cycle is nearly complete to add it.
