    And why not give air to the water flowing from the top of the screen. I just plugged pomke - so far without dice aerators - and the effect is great. Water flows down the screen foamed.
    And this is my box, screen and lighting - LED current on the tapes smd5060. The whole works without problems for almost 1.5 years.

    The new Upflow Algae Scrubber (UAS)

    Hello everybody,

    This is my first post here, I currently have a 6 month old 5g tank with just a small internal filter and a powerhead as means of filtration.
    I'm currently gathering ideas and equipment for my 15g tank and I would really like to keep it as simple as possible so I want to give the new ats design a shot!
    Currently I have 3 designs utilizing the uas principle:

    1) I call it "intank uas"


    This is the simplest and smallest design I could think of.
    It is just a small box for the screen, either lit by the display light or through the glass with leds.
    A small pump should be used to feed the scrubber with nutrient rich water.

    2) slim HOB uas.



    This design has a pump in a small overflow box and the water flows through the uas much like it would in a regular HOB filter.
    The Hob filter should be designed to accommodate a heater so the dt is less cluttered.

    3) less slim HOB uas.



    Pretty much the same as design 2, but the overflow box is just larger and could house a heater.
    The screen box is just way smaller then design 2.

    Some more info about this build:
    either a 10x10cm screen (4x4") or a 7,5x10cm screen (3x4").
    Will lit it with a diy 9x1W led fixture (6x 660nm, 2x 630nm and 1x 460nm).

    All input is welcome!

    Air flowing down the screen, on a submerged screen !

    Do you mean this http://http://algaescrubber.net/forums/showthread.php?1838-Co2-turbo

    If not, please explain how you do it.

    Thanks! I didn't really knew if I should post it here, but I guess I should have :P

    I'm closely following Doompie's progress, because we both live in Holland.
    He has given me some pointers and ideas which I took into consideration with my own designs.

    One of the goals I hope to be able to accomplish is having a pair of mandarins in this tank, so I sure hope that the uas will house lots and lots of pods!

    An interesting test would be to let the mandarins into the screen area; they would not eat the algae, but would target the pods.

    Perhaps just let them into a small portion of the screen.

    That is an interesting thought, but how could I do that? the only option I see is putting the screen in the display before a cleaning.
    All other options would stress the fish or cause problems with light spilling (I'm biased towards option 3 right now).

    I was thinking of an all-mandarin tank. Otherwise the other fish will eat the algae, like my tetra who has found a home there.

    #1 may not need the pump since the current generated by the airstone should circulate water. That's pretty much the design I'm going to try, when I get the time...
    You might want to put a lid on the designs to control salt creep. All those bursting bubbles will create a mess if there is no top.
