My lights come on at 6:00 am, ramp up for 3 hours, run full intensity until 4:00pm, then ramp down for 3 hours, turning totally off at 7:00pm. Shown below is a graph of 1 weeks ph readings. 100% of the time the reef’s ph bottoms out at exactly 6:00 am and peaks at 5:00pm.
I’m familiar with coral respiration but why does it peak exactly 1 hour post light intensity like clockwork. Is this true of all reefs. Just curious. Thx.
