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.



I don't have a biofilter but I have a veggie filter and stream. Is it
bad to turn the stream off?
