    Building a filter system, please advise

    My pond was build couple years ago. The filtration system was not enough to process the pond.
    After visiting my friend's pond, I am thinking to build a system just like one.

    The filter system will be using matala instead of Japanese mat.
    1st pool - 40 sheet of black matala
    2nd pool - 40 sheet of green matala
    3rd pool - 40 sheet of blue matala
    4th pool - 47 sheet of grey matala

    Please advice if there is anything I could do to improve the system.

    Thank you in advance.

    Please tell us about your pond. Dimensions, water movement, size and number of fish, maintenance schedule... and why you think your current filter isn't doing a good job.

    My pond is 25M x 10M x 0.8M depth (200cbm)

    Current filter system
    - Designed and installed by a local guy.
    - Capacity: 1cbm
    - Flow Rate: 9 cbm/hr
    - Filter Media - plastic beads and tiny Styrofoam beads.
    - Water go through a UV camber before entering the filter.

    Pond water is very green and unclear.
    I only see the fishes when I feed them.
    During the hot days, green foams floats all over the pond.

    My friend's koi pond is crystal clear. You can literally see the bottom.
    So, I am thinking to build a filter system just like his and hoping the new filter system can solve these problems.

    New filter system design:
    - Capacity: 14cbm
    - Flow rate: 80cbm/hr
    - Pond tune-over rate: once every 2.5 hour.
    - 1st bay - capacity 3.5cbm - black matala
    - 2nd bay - capacity 3.5cbm - green matala
    - 3rd bay - capacity 3.5cbm - blue matala
    - 4th bay - capacity 3.7cbm - grey matala
