    Oliver Knott: cleaning silicone seams

    Tips for algae removal

    Beautiful planted tanks made of high-quality white glass are getting more and more popular. According to modern standards such glass tanks are not manufactured with black, but with transparent silicone, preventing unsightly black bars blocking the view of a beautiful aquascape. In order to keep the bright silicone seams clean and free from algae, acuascaper Oliver Knott has a couple of useful tips in the following video.

    Using a modern edge fitting, the aquarium’s seams might be very thin, but over time algae may settle there. In order to stay visually appealing, the seams should be cleaned at regular intervals. Oliver Knott recommends weekly cleaning, even though algae films might not be visible, yet. This kind of regularity ensures that even the tiniest accumulations of algae are removed and prevents the forming of larger and much more visible algae colonies. Oliver Knott uses various cleaning tools.


    Special soft sponges for the removal of algae such as the Magic Cleaner Sponge used in the video, or the Seachem Algae Pads are not only suitable for cleaning the silicone but also perfect for getting rid of soft algae films on the aquarium’s panes. The soft material won’t leave a scratch in the aquarium’s glass.

    A toothbrush can be misused very well for algae removal on the silicone seams of the aquarium. A new toothbrush should be used, though, so there won’t be any unwanted toothpaste residue. The toothbrush’s bristles will even reach algae, sitting in the corner under the silicone lines. Oliver Knott also demonstrates in the video how to purposefully remove sludge and algae from hardscape such as driftwood and stones.
