Aqua Logic Cygnet EVO 2 Inline Electrical Heaters for ponds, aquariums and fountains AquaLogic

During the cold winter, Koi stop eating and live off their fat reserves, lowering their immune system. As the water begins to warm up, bacteria become active, and Koi can be in trouble. Keep your Koi strong all winter by heating your pond, keeping your Koi feeding consistently.

In the past, heating Koi ponds has meant running gas lines or propane lines out to the pond. Now with Aqua Logic Inline Heaters, you can have pond heating wherever you have electricity!

Need help deciding which heater to buy?    In a 24-hour period, a 2000-watt heater will raise a 2000-gallon pond about 10° in temperature.   A 4000-watt unit will raise the pond temperature in a 4000-gallon pond about 10° in 24-hours, etc.    In other words it may require about a watt per gallon to make significant changes in your pond.    The more significant the changes you need to make and maintain, the larger wattage heater you should purchase.
