I'm running 3 (1 master 2 slave) Pacific Sun BT-ES 120w LED
units on my 125. They are equivalent to 400w MH
. The clam on the sand bed is loving all that light.
I have some Acros that should love that light that bleached when attached to rock at the top of the tank. I also had an Aline Eyes chalice that bleached on the sand. My Candy Cane needs to be shaded too. I'll be more carefully with light acclimation in the future.
