Montis' can take a couple of days to adjust and show polup extention.
the pods, im assuming theyre amp. or tigerpods since they are visible, are just doing normal (cleaning) activity.
placement, IMO, is a little low for a 75G depth but, i would leave it there for a couple more days and allow it to adjust to your lighting.
N03 could be a touch high compared to what the coral is used to, some can handle as much as 5.0, but 10.0 is pushing it.
i would consider a 20% water change or filtration/carbon change at the least.
i would also consider changing to a 14K or a 20K depending on the wattage.
if its a 150W i would use a 14K, 250W or greater i would go with the 20K. :thumbsup:
