    What about watercress?

    Hi Joanna.
    Watercress likes to have a cold spell each year and thrives in cold water. I don’t know what area you are from, but if you get season changes, then yes, watercress would do well.

    I also have water celery and I put some water hyacinth in there. They get big, dark glossy green.

    If my bog is higher than my pond, why would I not want the water to flow down through the gravel and out through the bottom instead of going up and out like your plan shows? It would seem to be more natural. Just curious. Thanks.

      If you do it that way it may clog. I used to have it that way and it usually clogged once a year.

    I want to build a bog filtration system for my 5100 gallon pond but it will have to attach to a small stream. How do I keep the pea gravel from flowing into the stream? I can’t enlarge the pictures to see how your system keeps the gravel in.
    Thank you

    We have several bog filtration systems that flow into a stream and have never had a problem with pea gravel moving from where it was placed. I think it would take a really powerful pump to make that happen!
