How to best remove sludge without a vacuum?
Naturally! With our BioPond Sludge Removal Set, you can break down pond sludge between rocks and plants biologically and sustainably. Specialized microorganisms act as a kind of "pond sludge destroyer," gently cleaning your pond, permanently removing the sludge, and breaking down the invisible algae nutrients.





Enjoy peace of mind with cost savings and no sludge vacuum! This special set reliably breaks down pond sludge and existing deposits between stones and plants in a completely natural way. Additionally, it ensures optimal mineralization, keeps the pH level stable, neutralizes harmful pollutants, and increases the essential oxygen content in the pond water. Sit back, relax, and look forward to a clean pond bottom without strenuous cleaning work.
The set includes the following products:
- BioTeich Schlamm Stabil
- BioTeich Balance
- BioTeich Vital

FAQ about pond sludge
1. How does pond sludge form?
Pond sludge and deposits between rocks and plants are caused, for example, by the input of leaves, blossoms, or pollen. Dead algae, dead insects, bird droppings, and—if there are fish in the pond—excess fish food and fish excrement are also contributing factors. All these inputs sink to the pond floor due to gravity. Natural decomposition processes then create nutrient-rich pond sludge. These nutrients promote algae growth. During decomposition, foul-smelling gases can also cause unpleasant odors and bubbles on the pond surface, making the pond literally stink and threaten to "tip over."
2. How do I get the sludge out of the pond or how can I remove pond sludge?
In many places, so-called pond sludge vacuums are used. These devices work in principle like a vacuum cleaner. As mentioned above, you can vacuum away the visible layer of sludge, but by stirring up the invisible nutrients, you promote algae growth. A more ecologically sound method is gentle removal using appropriate microorganisms, which are included, for example, in the BioPond Sludge Removal Set.
3. When should you vacuum pond sludge?
Regularly vacuuming the sludge creates a vicious cycle. Nutrients are released and fuel algae growth. We recommend vacuuming pond sludge only once, namely when the sludge layer is already very thick, i.e., more than 5 cm high. After that, you can easily use the BioPond Sludge Removal Set. You only need to distribute it on the pond surface every two months.
4. How often do you need to clean a pond?
Once, if there is a thick layer of sludge. Otherwise, the BioPond Sludge Removal Set takes care of regular breakdown and prevention of the sludge layer and deposits on the pond floor.
5. What to do if the pond stinks?
If the pond smells, perhaps even like rotten eggs, pond sludge is usually the cause. A thick layer of sludge not only contains nutrients that promote algae growth but can also produce decay gases that cause unpleasant odors and bubbles on the pond surface. In this situation, you should vacuum the sludge once and then break it down gently and biologically.
6. Why shouldn't you use a sludge vacuum regularly?
A vacuum removes the sludge but, by stirring up the invisible nutrients, also causes them to become highly concentrated in the pond water. This strongly promotes algae growth. In the long run, regularly removing sludge with a vacuum will always lead to new algae growth or green, murky water. We recommend using a vacuum only once and only if the sludge layer is particularly thick.
