Autumn bacteria

In autumn, fallen leaves and organic waste accumulate in the pond and eventually form sludge. Discover our bacteria specially recommended for autumn to accelerate the breakdown of organic matter, keep your pond cleaner, and prepare the water for winter.

🍂 Less waste • Less sludge • A pond better prepared for winter

Why add bacteria to your pond in autumn?

Autumn is an important period for the pond’s biological balance. Leaves fall, aquatic plants begin to decompose, and organic waste gradually accumulates at the bottom.

Without intervention, this material can form a layer of sludge that will continue to decompose throughout the winter.

Using bacteria suited to autumn naturally supports the decomposition of this waste and limits its accumulation before the cold season.

Which bacteria should you choose in autumn?

At Foudebassin, we have selected different solutions depending on your pond and the water temperature.

Aquipond BactoVase Liquide
A liquid biological solution that is particularly useful when the pond accumulates leaves, plant debris, and organic matter. The microorganisms contribute to the gradual breakdown of waste and organic sludge present in the pond.

Microbe-Lift Autumn / Winter Prep

A formula developed specifically for autumn and winter. It combines bacteria and enzymes to promote the decomposition of leaves, sediment, and organic matter, even when the water temperature drops significantly.

Foudebassin’s advice

Do not wait until all the leaves are at the bottom of the pond.

Start your autumn maintenance as soon as the first leaves begin to fall:

🍂 regularly remove the largest debris with a net
💨 maintain good pond oxygenation
🦠 add bacteria suited to the season
🧹 remove as much accessible debris as possible before winter

The goal is not to make the pond completely “clean,” but to prevent too much organic matter from remaining at the bottom of the water throughout the winter.

A pond that is well maintained in autumn will generally be easier to restart in spring.
