Everything you want to know about a pressure filter

What is a pond pressure filter and why do you need a filter?

A clear and healthy pond is the dream of every pond enthusiast. Whether you have a small ornamental pond or a larger garden pond, well-filtered pond water is essential to prevent algae, turbidity, and poor water quality. One of the most popular and efficient systems to keep your pond water clean is the use of a pond pressure filter. But what exactly is a pressure filter? And why is it important to use a pond filter?

What is a pond pressure filter?

A pond pressure filter is a closed filter system where the pond water is pumped through the filter under pressure. This is in contrast to traditional flow-through filters, where the water flows through the filter by gravity. The pond pump pushes the water through various filter media such as filter foam and biological filter material. Thanks to this pressure, the water can go through several filtration steps and even be pumped upwards after filtering, offering great flexibility in creating waterfalls or streams.

How does a pressure filter work?

The water from your pond is first pumped through a filter foam package that captures all coarse debris, such as leaves, twigs, and fish waste. Then the water flows to biological filter material, such as BioCell or BioBall, to which beneficial bacteria adhere. These bacteria break down harmful substances like ammonia and nitrite, which would otherwise be toxic to fish and plants.

The VarioPress Pro-E series from AUGA® is equipped with an electrically driven backwash system. This makes cleaning the filter package easy and quick, without having to open the filter. The purified water is returned to the pond via the built-in UV-C lamp. This UV-C lamp kills floating algae and pathogens, ensuring clear and healthy water.

Before pond water leaves the filter clean and clear, it has undergone several purification processes. (Example: VarioPress Pro-E 55 and Pro-E 70)

Key features of a pond pressure filter:

Mechanical filtration: Removes debris such as sludge, leaves, and fish waste.
Biological filtration: Beneficial bacteria break down harmful substances.
UV-C lamp: Kills floating algae and pathogens, preventing a green pond.

Why a pond pressure filter?

1. Flexible placement of the filter

Since the filter works under pressure, you can pump the purified water upwards, ideal for creating an elevated stream or waterfall.

2. Compact and unobtrusive

Pressure filters are relatively small and can be partially buried, making them hardly visible in your garden. They are ideal to place together with the pond pump in a small filter pit.

3. Easy maintenance

Thanks to a built-in backwash system, you can quickly rinse the filter without getting dirty hands, making maintenance easier.

4. Clear water without algae

The UV-C lamp effectively combats floating algae and pathogens, keeping your pond clear.

What to consider when purchasing a pond pressure filter?

Pond volume: Ensure the filter is suitable for the size of your pond.
Fish stock: More fish means more biological filtering.
UV-C power: Especially for sunny ponds, a powerful UV-C lamp is important.
Ease of maintenance: Preferably choose a filter with an electrically driven backwash function.
Pump capacity: The pond pump must match the pressure filter and be suitable for pumping dirty water.

For which ponds is a pressure filter suitable?

A pond pressure filter is suitable for ponds from small to large, even up to 75,000 liters. Whether your pond contains only water or is populated with plants and fish, a pond pressure filter is practically usable everywhere.

How often should you clean a pond pressure filter?

During the growing season (spring and summer), it is advisable to clean the filter material regularly. This depends on the degree of pollution. With a backwash system, this is a quick task without opening the filter.

Extra tips for a healthy pond

Ensure a good pond pump: The pump determines the water circulation and must be matched to the filter.
Regularly refresh part of the pond water: Even with a filter, it is wise to occasionally refresh the water.
Use pond plants: Plants help keep the water clean and provide shade against algae.
Watch out for overpopulation: Too many fish cause extra pollution; keep this in balance.
Regularly check the water values: Good pH, ammonia, and nitrite values are crucial for a healthy pond.
