Just a mystery. My tank temp goes up at night. Can't figure it out.
My chiller comes on at 80 degrees. Heater is on at 78 degrees (winter only).
All day, the chiller doesn't come on. At night, the chiller cycles the tank temp from 80 down to 79.5 several times.
The room has an air conditioner - always between 78 and 79 degrees.
During the day, the lights are on, at night they're off.
Circulation and sump pumps are about the same day and night, a little less flow at night.
UV light is on 24/7. A heat source, yes, but no difference between day and night.
At night, there is a small refugium grow light. (I turned it off for a couple of nights, no difference.)
My theories -
My condo building absorbs heat all day, then radiates heat into the interior at night.....
Something about CO2 (don't know what)...
No humans at night to walk around and create air circulation...(could maybe add a little nighttime circulation fan for the room, but the chiller is doing fine on it's own)
Anyway, no crisis, just a mystery.
