"Scott M." wrote in message ... I have a pond that is around 3 1/2 feet deep. Right now, my thermometer indicates that it is 0.1 degrees Celcius down there at the bottom. The Koi and Goldfish are still alive but isn't that a little too cold? It's not even winter yet. I have a bubbler to keep the surface clear and a floating 1250 Watt heater if I need it later, but I was thinking of lowering a low wattage heater to the bottom of the pond just to make sure the poor fish don't freeze. Is this a good idea? BTW, my pond photos are at http://pg.photos.yahoo.com/ph/murchi...mK9ICBHtrk1kvG Scott Hi Scott, The general advice is to put in a bubbler to keep the ice open. You might also need a floating de-icer in colder climes. However, being paranoid. I built a cover for mine and put a 300 watt heater on the bottom. The heater hasn't kicked in yet, as the pond is still 42F. My pond is not quite as deep as yours, so I was concerned that it would become a solid cube of ice in January. If this works out well, I may try to raise the temperature above 50 earlier in the spring, so I can start feeding earlier. Although I suspect 300 watts won't be sufficient. Where are you located BTW? |
