    upside down sand bed!!!!!!!!!

    ok so now i have actually made the decision to move the sump to the basement and its gonna be a 65g sump. I have just read a article regarding upside down sand beds (UDSB) i was wondering wether any one is running one of these or has any experiences with them.
    The article stated that it would greatly improve the sump's performance.
    I wikll be using the 65 and have one half for equipment and the other half with udsb, what do you guys think?

    The article was in vol 7 of the MarineFish & Reef USA 2005 Annual. It was called Sump Improvement by DR Charles Mathews. The magazine has some very good articles.

    If you cant find a copy let me no.

    Weird but they dont seem to have a web site.

    Well, I've heard of the magazine and have read many of them, but I have not heard about those upside down Flint Rubble bubble cake sandbeds...
    I'll take a look at the magazine and read it.

    " i have experimented with a no. of designs but the most succesful has been an udsb"
    "The inflow to the sump is directed into a plenum one end, where staggered pvc pipe supports allow a rapid flow around bends and then up through an outlet at the opposite end of the sandbed. This design gives you the effect of 3 sand beds: An upsb, a thin layer on the floor of the aquarium and then the conventional top surface"
    Dammit wheres my scanner.

    An excert from the article, laters peeps!

    "obeserved for over a year this design worked very well. I used crushed coral for the bottom layer (placed on a fibreglass screen over the staggered 2" pvc) fine aragonite for the surface layer and 1" flexible pvc for the inflow and outflow.
    The bottom of the aquarium did not progressively accumulate organics. With sufficient flow a thin layer of mud develops and seems to be limited by increasing flow in any areas that might otherwise develope constriction.
    In this design the refugium area is effectively tripled, as is the production of surface area generated plankton. The design allows a slight upward pressure and also increased water movement through the sand grains."

    Enough already Derik go out and buy the mag, its worth it!
