Typical pH swing?

What's the normal pH swing throughout the day and night? My pH will peak at 8.24 at about 5:00PM and bottom out at 8.12 at about 5:00AM and then start to climb back up around 9:00AM when the lights start ramping up. I don't suppose a .1 swing throughout the day is too bad is it? I run my refugium light at night to offset the swing and my LED moon lights stay on at about 3% all night except for complete darkness from 2AM to 4:30AM.

Wow! Don’t look for problems you don’t have. That pH swing is nothing! Sit back, be happy, and enjoy your tank. You don’t have a pH problem at all.

Agreed. Watch alkalinity, calcium and magnesium and don't worry about pH.

Sweet. I never want to get to the point where I take things for granted so if I'm unsure I always ask the pros! Thanks guys.
