Hi! Im running a 6 bulb t5 on my 65 gal mixed reef. It has a few acros, montis, stylos and a large LTA on the sandbed. Im getting about 265 par on top of the rockwork and about 130 where my nem is. Im switching to xr15's. I would appreciate suggestions for power percentage to start acclimation. Or any other advise. Ive had mixed results with LEDs on my other aquariums. Thanks!
