Timer to turn pond pump on at dawn and off at dusk?
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? |

Not doing so can risk killing off the beneficial bacteria in the filter, and cause nutrient/toxin build up in the pond. |

Couldn't you just use one of those timers from Wal-Mart that turns on and off based on the actual time itself? -- Gareee's Homepage: http://www.fortunecity.com/tattooine.../mainframe.htm Remove Delicious spam to reply |

Yea, I just thought it would be nice to have it come on and off at the right time so I wouldn't have to adjust the timer. |

Is it bad to turn the stream off? http://members.cox.net/michaelshaffer/pond1.jpg http://members.cox.net/michaelshaffer/pond2.jpg http://members.cox.net/michaelshaffer/pond3.jpg |

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. |

Do you have fish in the pond, if so, how many,
what kind are they and how big are they? Fish is your consideration if you can turn a pump on and off. Few fish, small fish and you can turn off the pump. Large fish, lots of them you may end up with dead fish in the morning. Plants in the pond go from making oxygen in the day to *using* oxygen at night. Turning off the pump just adds to the oxygen debt over the night hours. Few small fish can deal with it. Lots of large fish can not. Hope that helps! kathy :-) www.blogfromthebog.com |

I don't have a biofilter but I have a veggie filter and stream. Is it bad to turn the stream off? If you have an aerator to keep the water oxygenated, the fish will be ok. However, you should always have water running through your veggie filter to keep the plants fed and the nutrient load down. That is, after all, the purpose of having the veggie filter in the first place. If your pump uses too much electricity, perhaps you should look into buying a more efficient one. http://members.cox.net/michaelshaffer/pond1.jpg http://members.cox.net/michaelshaffer/pond2.jpg http://members.cox.net/michaelshaffer/pond3.jpg That's a nice pond, by the way. |

You might want to look into buying a cheaper one that uses much less electricity and that you can keep on at night. That way, you can turn the bigger pump on during the day, and then switch to the smaller pump at night. |

Michael,
In the winter when you didn't have the pump running the water was colder and therefore naturally held more oxygen and the fish metabolisms were lower since they were colder. Since those are some pretty big fish I wouldn't risk losing them by not having some form of aeration. You could probably find something that would agitate the water for less wattage at night. James |

You might try an aquarium pump to bubble at night. Less cost and good
oxygenation...Don't know how much air needed. Jim Michael Shaffer wrote: 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? |
