Question
I have a pond it is 6 feet wide, 17 feet long and is about 28 inches deep (1st year). What do I need to know to get ready for winter?  Primarily do I leave the pump and waterfall running during the winter. I live in Ohio and it does get cold with freezing weather often in winter months and do I have to worry about the top freezing? Any info would be helpful.

Answer
Hi,
I keep my filtration running all the time but in winter I turn the pump down so that it is a lot slower ,but we don't get the cold and freezing winters that we used to get years ago.I don't know how cold it gets in Ohio but you must keep a part of the surface of your pond clear of ice so that any foul gases from decaying leaves can be dissapated into the air.
