    Hi Guys

    I have been doing some research on fluidized filters and I am thinking of building a small internal fluidized filter, using pool filter sand as the filter media. Anyone ever tried this?

    Regards
    David

    Why PFS? Why not k3 media?

    Hi. I haven't tried this before, but I have heard of people and friends doing this. They say it is quite good and helps with filtration a lot. It is worth a try, in my opinion.

    I dont think k3 media would be effective in this size filter as its not going to be very big, probably max 2 liters. Is k3 even available in SA?

    Ah, yes so what I understand is for fluidised you need LARGE volume.
    Yes, there's K2/k3 available down the road for dirt cheap. If you want to try it pm me and I'll post you some.

    @David Kusner ... Fluidized filters are awesome but I dont know if a 2l space is worth doing fluidized...
    You need volume to really reap the benefit

    We running a fluidized bed on a 3.2m x 1.2m x 850 tank but the fluidized section of the sump is probably 500 x 650 x 650
    I suppose you can do it but dont know if that small amount of media will provide more filtration than if you had to fill it with matrix
    You have to leave space for the media to move so in a 2l section, very little media will be able to fit and leave space for it to move
    I could be wrong..

    there is a local version of k1 witch is pretty cheap
    tried to do a sand fluidized bed a few time, always been far more effort than positive gains made to the filter.
    using local k1 in a sump now, stopped using air pump cause the noise level was too much, needed 30ltr per minute for it to fluidize correctly and when it work it was great. now using a 6500ltr water pump far quieter but quite a bit less effective.

    on new tank i am doing i am not using a fluidized bed at all.

    What is the goal for building a 2l filter like this?

    I would rather do a water polisher of that size.

    The Water polisher is good, but only that a short term solution to give a quick water polish. I am looking to compliment the current canister filtration with a more permanent internal option, like a fluidized sand filter.
