Winter Advice
So Before Winter Has Arrives... Hopefully you are reading this before winter but if not, it's never too late! Here are a few thoughts to help you get through the cold winter months with your water feature... If you have fish, you must keep a hole in the ice for gas exchange.

Carbon dioxide is also produced by any decaying organic materials in your pond -- leaves, dead plants, muck in the pond bottom. Often times if there's a fish kill it's because of the carbon dioxide build up more than the lack of oxygen. So how to keep this hole in the ice? Use an Aerator -- An aerator with air stones placed just under the surface of the water will agitate the water enough to keep an opening most of the winter. There may be times when the temperature is in the single digits for an extended period of time that it will ice over, but this is rare. Plus an aerator only...
