Some of my pumps remain on at low throughout the evening. Then when my nanobubble scrubber comes on my recirculation pumps come on and alternate at 30%. They go off when the nanobubble scrubber goes off. They are on in the evening/dark like this from 22:00 to 04:30. Then I have a sunrise/sunset schedule that comes on at 09:30. Then day schedule at 11:00 followed by another day schedule causing a standing wave at 16:00 to 20:00 and then ramping down again with the sunrise/sunset schedule till 21:00. Every two hours from 09:30 till the end of the sunset schedule the pumps alternate at no specific pattern at 100% to mix the detritus up. I do scheduling with my pumps like this to better mimic the natural reef. In nature, there is more wave action on the reef during the day as the sun comes up and mellowing out as the sun sets. As things heat up there is more wind and therefore more wave action, for the most part. Does this all make a difference? I don't honestly know but everyone in the tank seems happy.
Nice! Love the detailed reply on a specific program. That was excellent.
