    What is your Idea about using Kenaf as bacteria house and media in barrel filter?

    Hi,
    last year a friend made a pond bio filter from sponges with 200L barrels, it was looking well working today asked my idea for a organic material was lava rocks and gravels but he was thinking about using Kenaf textiles.

    what is your idea about?

    Isn't kenaf a plant fiber? I would assume it would decay in water, but am not familiar with it. My guess is that it might work OK at first, but would become a negative itself when decay set in.

    I think it is best to use a material that does not degrade in water over time. That is why plastic media are so successful. (Ceramic media also, but much more expensive.)

    Thanks Maike, in my experience Kenaf decomposing in 3 years under the soil but I don't know about resistance under the water.

    Yes, I agree with you Yesterday I find a Kenaf textile company, and asked about it's resistance in water, they don't have such this tests. But I found in some papers this material is easy decomposing if molded.
