All the photoelectric timers I've seen are opposite of what I need. Is there a
timer that turns the power on at daybreak and off at dusk?


If you have fish and a biofilter, it is always best to leave the pump running.
Not doing so can risk killing off the beneficial bacteria in the filter, and
cause nutrient/toxin build up in the pond.



The only reason I wanted to turn the pump off is it uses about 460 watts
of electricity, otherwise I would leave it on all the time.
