    Hi All,

    I'm currently with a 3 ft inbuilt sump reef aqua...

    Thinking of upgrading to a 5 footer with a 4 foot sump comprising of a refugium beneath my main tank....
    (Once you caught the reef bug.... you are stuck)

    Any one out there with a refugium????
    Does having a refugium helps in nitrate reduction...

    Would be glad if details or experience could be made known...

    Hi Phang,

    Sure, a refugium COULD help to reduce your NO3s if it's set up right. All you need is a DSB in it, with LR, some macroalgae, a lighting setup either on RDP or 24/7. Just throw in some cleaner shrimps, hermit crabs, sand sifting sea cucumbers, trochus/turbo snails, and you should be home free. Just remember that the sump has to be designed in such a way that the water flows OVER the sand bed, and not THRU' it. If you had say, a 6" sand depth, it should help quite a bit.

    Rgds,

    Roger

    Hi

    Thanks for the infor,
    When u refer to the water not flowing through the sandbed, you are referring to not using UGF...rite???

    This is my ... 4 footer sump with a refugium.

    Water will flow into 1/2 feet of filter media and overflow into the refugium of 2.5 feet and overflow again into 1 foot of media again and into a reservoir.
    Water is definitely gonna run way above the sandbed...
    Understand for denitrification to take place effectively, must have slow water flow movement...rite ????? so gonna slow the flow down by larger outlets...

    Running on 2 x 55W 10000k PC and 1 x 36W 6500K PC.
    For the Refugium, Planning on a 3 inch DSB, lots of liverock and Cauplera.
    Hmm, Maybe a seahorse setup would be interesting...

    3in DSB is not enuff...at least 3.5in n above.
    i hv a 3ft refu in the sump n dsb in main tank. both do keep no3 down.
    Acroporids and Tridacnids

    ----------------
    pls kindly read up on the seahorse keeping before attempting on the idea.. it takes lots of dedication.. let alone.. it can only be a species tank....

    Would NO3 be at 0 levels if I apply the recommended inches of Sand????

    4 inches would be roughly 10 cm deep... means only have 35 cm of height space for aquascaping....

    What's the recommended depth than for the main tank???

    If a DSB is applied to the refugium, would there be a requirement for DSB for the main.
    Any other alternatives????

    Phang,

    Yes, definitely no UGF plates. Just bare sand on the bottom.

    Yes, flow can be slow, but you don't need to use large-bore pipes or anything like that. Usually I just set mine up with a bit of modification to a regular sump filter. The 1st partition in the filter can be retained. After this is the refugium with the sand bed. You just need one more partition made from a single piece of glass stuck right at the bottom, after the sand bed to block it from the return pump. Depending on how deep you want the sand and water to be in the refugium, just make the last partition height accordingly. E.g., If the refugium SB is 4", you might want to have a few pieces of LR there jutting up another 3" from the bed surface. The last partition should then be about 7" tall.

    Poor attempt at drawing here :

    * SNIPPED * - doesn't work

    What sort of media were you thinking of using in the 1st and last compartments?

    If you want to use DSBs, they should be at least 3-4" thick. In the sump, you can increase it to 5" even.

    Rog,

    Thanks for the infor.

    Actually I'm thinking of a 3 inch depth for my refugium and keeping my maintank SB to about 2-3 inches..

    I will customized my sump (inbuilt) refugium which is about 4.5 ft..
    1st half ft to be used for mechanical filtration.. before water flows into the refugium. tank height estimated to be 2 ft... will try to keep the water height at 1.5 ft.
    The water from my refugium would seep into another compartment comprising of my filter elements (thinking of cellpore), bioballs etc... then into a 1ft by 1ft reservoir.

    Would place my skimmer there.
