Do u have damsel? Many species of damsel spawn underneath the staghorn branches. They will clear out an area under the branches if staghorn and lay their eggs

No Damsels at all. Seems like they are only on the bottom (shade) side. To be more like your tank Anthony I added 3-250W Metal Halides about a week ago. Slowly on ramping up run schedule. Par is 280 when on.
