You should always check your PH late in the day. It will probably be where it needs to be. Early in the morning it will probably be low. That`s why I always suggest checking in the evening after the lights have been on a while.

I agree, try to test later in the day around the same time. Your pH will drop after lights out and raise after lights on.
If you have a lid on the tank that will limit the O2 exchange and lower your pH as well. In SW, O2 exchange happens are the surface or the water (water ripple)....Also, I believe your tank is still new and your pH readings will be all over the place until it settles down.....
