Filter Media Filter Media Dennerle

Dennerle filter media in this category are designed for different tasks in nano-aquarium filtration. The range includes biological granulate, active carbon, AlgenStop media and replacement pads or sponges for the compatible SkimFilter.

Choose the product according to the filter model and required function. Biological granulate provides colonisation area, active carbon adsorbs selected dissolved substances, and algae-control media or mechanical replacement elements work differently. They are not interchangeable even when their dimensions appear similar.

Check compatibility and pack contents before ordering. Use adsorbing media only for the intended period and monitor the relevant water conditions. Clean mechanical elements carefully and avoid replacing all biologically active media at the same time without a specific reason.
