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.
