Protect your Koi from the cold winters and treat your koi to the best Koi Pond Heaters!
Koi Fish immune systems are at their best in steady water temperatures around 75 degrees. 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 which allows you to continue to feed your koi all-year long.
