Biofilter (plant filter tower)
Biofilter: Plant filter tower
A plant filter tower is the solution for creating height differences in the pond. So you can easily place a plant filter in a deep pond. With pond crates, filter plants, pond substrate and bacteria, you have everything you need to create an optimally functioning plant filter in one go. This biological pond filter acts as a natural biofilter for effective water purification, completely naturally.

Loose pond crates
Is your pond very deep? Simply add additional crates below the top layer to raise the filter tower to the perfect height.
Step-by-step plan for making a plant island with pond crates
Pond crates are perfect for creating height differences in a pond. They are easy to snap together, and with three crates you can create a 40-inch elevation. Fill the bottom two crates with substrate for extra strength.
In addition, you can use pond crates to make a plant island. Stack a few crates, fill the bottom one with substrate and place six baskets of aquatic plants in the top crate. Make sure the top crate is 1 cm above the water to protect plants from fish.
Check out our guide below to create a Koi-proof island.
Step 1. Calculate how many crates you will need.
Measure how deep your pond is and calculate how many crates you need to make the tower of crates the desired height. Each crate is 20 centimeters high, so with three crates you can make an elevation of 60 centimeters unless you put plants in the top crate, then your elevation is about 50 centimeters.
Simons advice for pond crates
Use 3 crates to make an elevation of 60 cm.
Step 2: Fill the bottom crates with a layer of substrate (optional)
Fill the bottom crates with a layer of substrate of about 10 centimeters. This ensures that the crates are somewhat weighted so that they stand firmly. Also, the substrate is an attachment for pond bacteria so the tower will also serve as a large filter.
Simons advice for pond substrate
Use 1 bag of 20 liters pond substrate per 2 pond crates.
STEP ONE - pond substrate - 40 liters
- 40 L covers 1 m² ↥ 5 cm
- Heavy duty quality for the best filtration
- Extra porous: optimal plant growth
Step 3: Plant placement
Stack the crates in the pond in the desired location and to the desired height. Make sure that the edge of the top crate is about 1 centimeter above the water surface so that the fish cannot demolish the plants, but can only nibble on them a little.
Simons advice for aquatic plants
Place a total of 6 baskets for a full crate or go for a complete package.

Plant filter tower
Benefits of a plant filter tower:
- Natural filtration system: no electricity required, works with plants and bacteria.
- Space-saving: Ideal for smaller gardens or ponds.
- Easy to maintain: Only occasional plant touch-ups.
- Suitable for any pond: Functions well in both fish ponds and natural ponds.
How does it work?
- Water intake: pond water flows through the tower
- Filter layers: The water is filtered through pond substrate, which traps dirt particles.
- Plants: Plant roots extract nutrients (such as nitrate and phosphate), reducing the chance of algae.
- Back to the pond: The purified water flows back into the pond.
Want a low-maintenance, natural solution for clear pond water? Consider a plant filter tower. It's an eco-friendly choice that works without chemicals or energy consumption.
Biological pond filter: The best biofilter for natural water purification
What is a biofilter?
A biofilter is a type of pond filter that uses biological filtration to remove pollutants from water. This is done through beneficial bacteria that settle in the filter media and break down organic waste and pollutants such as ammonia and nitrite. Biofilters are essential for maintaining a healthy biological balance in the pond, especially in ponds with many fish.
Benefits of biofilters
Biofilters offer numerous benefits for pond maintenance. They provide a natural and environmentally friendly method of water purification using biological processes. This reduces the need for chemical additives and ensures a stable and healthy pond environment. In addition, biofilters help control algae growth and improve water quality, resulting in clear and healthy pond water.
How to choose the right biofilter?
When choosing a biofilter, it is important to consider the size of the pond and the biological load (the number and size of fish). Choose a biofilter with sufficient capacity to effectively filter the water. Also consider the type of filter media used and the availability of sufficient surface area for beneficial bacteria to establish themselves. A well-chosen biofilter contributes to a stable and healthy pond environment.
