Beautiful tank and great thread, Josh.
Way, way back on page one you mentioned your lighting schedule - "I use 3 250w metal Halides (3hrs a day) with 2 72' super actinic VHO (3hrs) and 2 60" reef brite xho blue led (10hrs)".
Are the VHOs on at the same time the halides are on, or are all on at different times? I've read in some threads by other big-time zoa players that the shorter but intense full-spectrum photo period coupled with longer lower intensity periods is what they believe makes their zoas grow such large and fat polyps. Just trying to understand how intense that 3 hour period you are using actually is, because you sir are growing some amazing corals.
