    Filter configuration

    I am planning a new pond and thinking of using both J-mat and fluidised bead (still debating on precise media). The pond itself will be approx 60tons with a 5ton (hopefully) settlement vortex. I am wondering whether:

    1. the J-mat should precede fluidised bead or after? or

    2 .the J mats should run as a series and the beads in a separate one?



    Thanks for your insights

    wow, im exactly in the same situation ...

    56 tons + 7 vortex units 1meter diameter 2meters deep
    3 of the vortexes are for settlement ...
    3 are for moving bed
    and 1 for j-mat (also wondering to put before or after moving bed)

    im leaning towards bed first ... being self cleaning and all

    Thats what I initially thought but putting the fluidised bead first could run the risk of the screen clogging up.

    Have you thought about running the filters in parrallel instead of in a series?

    Is your pond already setup and how much media (volumewise) do you intend to use?

    Settlement, fluidized bed, j-mat.

    Put a microscreen in the settlement and don't worry about the fluidized bed getting clogged.

    Jason,

    With the microscreen, are you referring to a estrosieve/pond sieve (pardon the spelling if I have it wrong) type setup or just a mesh to trap the fines?

    If the latter, then it will just move the problem to the settlement chamber instead wouldn't it?

    Microscreen; like the W.Lim VMS or Answer or *sieve. Self cleaning so you just dump the first chamber daily and don't need to worry about solids getting into the following chambers.

    The mesh size depends on algae growth and amount of solids. I think a 500 or 250 micron should do fine. With jmat in last chamber you could go with a 500 and let a little bit get through.
