EcoGerm Silt

A natural biological agent in the form of granulate with active oxygen, designed for reducing bottom sediment in garden ponds, fish ponds and bathing pools. Contains selected bacteria strains that accelerate the decomposition of the organic matter accumulated at the reservoir’s bottom. The granules easily penetrate the bottom sediment structure, which quickly triggers the sedimentation and bioremediation process. The bacteria introduced into the water environment effectively activate the process of ammonia and ammonium compound oxidation into nitrates, which are subsequently released into the atmosphere. This way, the water ecosystem remains in a state of biological balance, which is necessary for the proper functioning of any water body.

The EcoGerm Silt Agent

  1. Neutral to the environment and safe for people, plant, fish and other animals in a water reservoir.
  2. Can be safely used without the need to periodically suspend the operation of the reservoir.
  3. Accelerates the decomposition of silt and bottom sediments by decomposing organic substances (dead plant parts, fish excrements, unused feed residues, etc.).
  4. Fixes heavy metals.
  5. Improves water clarity by reducing chlorophyll levels in the water.
  6. Improves fish condition and health of fish and other water animals, fostering population growth.
  7. Provides better utilisation of feed in farming ponds.
  8. Acts in a localised manner and quickly penetrates a muddy bottom.
  9. Available in the following packaging sizes: 1 kg, 5 kg, 10 kg and 25 kg.


Used for: garden ponds, fish ponds (farming), bathing pools, natural ponds.


Application: shake before use to thoroughly mix ingredients, then spread the measured dose of the agent evenly on the water surface. Use twice a year – in spring and in autumn, or as required, depending on the level of bottom sediments. For heavy silting, apply several times a season, but no more than once every 30 days. To accelerate sediment reduction and algae control, it is recommended to use the microbiological agent EcoGerm Lakes in conjunction.


Dosing: 10 g for every m² of the water surface.


Storage: store tightly closed packages in a dry and cool place. Keep out of the reach of children and away from sunlight and heat sources.


Things worth Knowing

EcoGerm Silt is the most effective in water at temperatures above 10°C.

EcoGerm Silt has the form of a fast-acting granulate, which enables localised application at selected spots.

The active oxygen addition in EcoGerm Silt greatly accelerates organic matter decomposition in the bottom parts of the reservoir.

Biological agents may not be used in combination with disinfectants or antibiotics - they may not be dissolved in chlorinated water.

Regular use of EcoGerm products guarantees clean and clear water all year long.

Frequently Asked Questions

Can EcoGerm Silt be used as a replacement for other EcoGerm Silt bacterial agents?

It cannot. EcoGerm Silt is a microbiological preparation with a strictly specific effect. For a general improvement in water quality, regularly use all EcoGerm line products: EcoGerm Starter, EcoGerm Ponds and EcoGerm Lakes.


What is the difference between EcoGerm Silt and the other silting reduction agents available on the market?

EcoGerm Silt is a granulated microbiological agent with an active oxygen addition. It can be quickly and precisely applied. The granules sink and fall to specific spots in the reservoir, and the active ingredient accelerates the process of sedimentation and bioremediation. Thanks to these qualities, EcoGerm Silt acts much faster than the competing products, and the effects of its use are clearly visible.


When and how to use EcoGerm Silt so that it is the most effective?

EcoGerm Silt is best used twice a year (in spring and autumn), or when needed, as dictated by the level of silting and bottom sediments in the reservoir. The agent can be added without removing the fish first (it is safe for the environment, people and animals). For best effects, apply EcoGerm Silt together with EcoGerm Lakes bacteria.
