I use the seasonal table to run my Hydra's via the If Sun commands. I do a sunrise and a sunset. This I have been using for years. I have an extra Hydra that I have on my refugium.
Here's what I am trying to accomplish: when the main lights go into start their sunset cycle the refigium lights start sunrise, vise/versa when main lights start sunrise the refugium starts sunset. The "daylight" cycles and sunrise/sunset cycles run opposite of each other.
I think I am over thinking it. It should be simple in my mind I've play with so many code combinations I cant seem to get it eaxctly right.
