    This is the moustached Danio, Kris (profile here).

    Got any pics of your new Danio? We’ll see if we can help you ID it.

    Ahh that’s a gutter about your cichlids Kris, sorry to hear that.

    Soo, you wanna split that list of fish between a 120L and a 180L, yeah?

    Oh, one more thing.. just found this article:

    QUOTE(fins.actwin.com)
    Diana Berberich has a noise Fluval 304, replaced all the
    parts in the impeller assembly and it still has a clatter.
    What’s the matter?

    I have had similar problems with Marineland powerheads.
    Within a the warranty period, Marineland will send you a
    new rotor. If that doesn’t work, they will send, you
    guessed it, another rotor. If that doesn’t work, they will
    send a new powerhead. Or so has been my experience.

    These two-pole, permanent magnet rotor, AC motors are
    extraordinarily simple. In motors of this type, people
    often say there is only one moving part, meaning the
    magnetic rotor, which spins within a “rotating”
    electromagnetic field generated by a pair of coils housed
    around the rotor (usually sealed in epoxy or some other
    potting material). If the rotor is the only moving part
    and it ain’t rubbing, what else could possibly make the
    clatter? Well, probably the second moving part that they
    all have.

    The common culprit on Marineland powerheads is the
    water-vane wheel, which is the small set of blades that
    actually spin the water, forcing it through the powerhead
    or pump. These wheels are not fixed to the rotor shaft but
    can rotate freely about 225 degrees or about 3/4 of a turn.
    If these wheels are just a tad too loose, they will cause
    the pump or powerhead to clatter.

    Old rotors can have wheels that have worn loose. This is
    one reason most powerhead manufacturers forbid using on/off
    cycling timers (so-called wave makers) on their powerheads;
    it promotes an early end of quiet life for the rotor wheel.

    *But new rotors can have wheels that are too loose,*
    although the rate of occurrence seems to vary by
    manufacturer. In my small experience, Marineland has a
    high probability and Eheim an extremely low one. (How many
    Marinelanders say their Magnum is quiet vs how many
    Eheimers?)

    Other factors that can cause a clatter: worn or poorly
    fitting bearings or misaligned bearing seats. But I think
    this is a rather rare reason for pump clatter. Bearings
    can be replaced if they are at fault but seat alignment can
    be harder or easier to deal with. It can be harder because
    the seat alignment is generally fixed by the manufacture of
    the pump housing. But it can be easier because, with some,
    a little push here, a little realignment pressure there and
    you can help to quiet a noisy pump — but only if bearing
    seat alignment is the culprit in the first place.

    If you’re having trouble even after replacing the impeller and shaft, have a browse through that ^.

    Well mate, I had a bit look around on google for you and noticed the text on this auction:

    Fluval 304 replacement impeller shaft assembly.

    QUOTE
    This Auction is for brand new and boxed Hagan Fluval impeller shaft assembly for the 304/404 filters.

    Please note that there are two types these. This model is for use with models prior to July 2001 and the curved blade impeller.


    So, there’s two types of impeller. Which be yours young Sir?
