It is important to continue to add beneficial bacteria throughout the year- even during the colder months. By adding beneficial bacteria you are ensuring that healthy bacteria continue to colonize and keep the ecosystem balanced. When first starting up your pond in the spring, be sure to add bacteria 3 times a week for the first 3 weeks and then just once weekly thereafter.
During the colder months it is suggested to add a strain of bacteria that is formulated for cold water, or specifically made for fall and winter maintenance. The heterotrophic bacteria contained within the cold water formula thrive in lower temperatures. The formula for spring and summer maintenance contains bacteria that function and thrive in warmer temperatures.
