    Hi JC, it mentioned about fluidized bed filter.
    Is it essentially a very efficient bio filter?
    Any advice on it?
    What's the difference between this and a undergravel filter?

    The fluidized bed filter he referring to is basically a FR. He is using it with Zeovit media. Many SPS folks love Zeovit cause it helps to bring out the color of the SPS. For more info, check out http://www.zeovit.com

    The fludize bed filter he is using. http://www.deltecaquariumsolutions.com/Flurec_4.php

    Is a fluidized bed filter, basically filter media suspended in mid-water to act as bio filter?

    Question. What's the main difference between fluidized bed & under gravel?
    It seems both work on the "same" concept, using media to house aerobic bacteria as water passes thru it.
    Why would undergravel be a nitrate factory?

    JC.. in this case if we just put substrate in one of the chambers of the sump wouldnt that act as an FR??

    For undergravel, u can't put any filter media. Even if u do, u can't replace them unless u tear down ur whole setup. Undergravel filer tend to choke up pretty easily, thus nitrate factory. A FR typically is used to adsorb some chemical in the water like PO4. Thus more of chemical filtration than Bio.

    Substate in sump is DSB concept not FR. As mentioned by Daryl, a FR will basically keep the media suspended in the water column.

    make sense on the choking part.

    what about ranmasatome's question on putting substrate in 1 of sump compartments?
    over time may also choked, but removing & cleaning is possible.

    probably that's why fluidized filter have their media suspended, thus no choking problem.

    thanks bro...

    Oh. As I mentioned, ranma's idea is basically a DSB (deep sand bed) concept. It make sense for bio-filtration and I was using it. Basically, its used to remove Nitrate from the tank. http://www.wetwebmedia.com/deepsandbeds.htm

    The worrying part is, with DSB, ppl think no need to change water...
    So you were using DSB... what's your depth? is it using grade 0 coral sand?

    I've read from RC (ReefCentral) a few months ago that having a DSB and not maintaining it might be bad for the tank. There's an occurence called 'Phosphate Burping'. The phosphate that are trapped in the sandbed will eventually be pushed out by itself. And the corals and livestock will be badly affected. One of the members there even has a picture of a before and after occurence of the 'phosphate burping' occuring in the ocean. Don't ask me to link it here coz it's quite a task searching for it. Paying members there has an advantage in that they can use the search button anytime.

    so in this case if we use DSB for tank then need to clear it out like once in 2-3 mths?? wouldn't this clearing out cause po4 burping as well?? if dont use DSB then use waht to get rid of nitrates?

    Imo, the problem of DSB will only occur after >3yrs of usage. Thus its only a minor problem which can be resolved. Another thing of not using DSB, if u are not over-skimming or if u are using a bare-botom/thin sand bed, your tank will properly nvr able to keep hard coral in gd health without a DSB. Thus I'll always recommend usin DSB to new comer unless they are willing to fork out >$500 just to get a gd skimmer as startup.

    Yup. I was using DSB. Its C0 sand with 5 - 6" thick in my main tank. My NO3 is always zero based on Salifert test kit.

    Hi Ranma, why do u need to clear out a reef tank in every 2-3 months?

    Cheers

    You need to maintain the dsb by not letting any waste or leftover food settled on it overtime. A good water circulation is essential and if there is a dead-spot in a reef tank, you would noticed it as diatom might be appearing on that spot.
