    Okay so i've decided to design a new tank. Been waiting for this for some time.

    This is my planned size.

    Tank
    120(L) x 60(W) 50(H)
    Water will be at 48.
    I'm thinking of going rimless with this tank. Probably 12mm to be safe.
    3 panes being starphire.
    Skinny overflow.
    Still wondering how i should do the return so that i dont have water running back into the sump.

    Sump

    I will use my current tank as my sump.
    120(L) x 45(W) x 45(H)
    I will start posting pics of what i think the sump will look like.
    I want to have a DSB with LR on top and some sort of frag section. Still wondering if its worth using DSB or going with bacteria and vodka dosing.
    Reef Octopus 100 Int Skimmer
    Phos Reactor + Carbon Reactor

    Lighting

    I'm still pondering on this depending on lighting.

    probably 2 x 150W MH and 2 x actinics

    Here's the tank design so far.

    nice project

    smaller tanks with an overkill of equipment and very manageable

    my comment on the return: why not put the return as a reverse flow and place it under your rockwork to flush anthing that wouldve settled there..

    12mm will be fine for rimless ion this tank but you may want to consider going either 50mm with your overflow or spanning it over a wider distance over the back to allow for a stronger return pump to be used.

    enjoy, 4ft tanks are my favourite size tanks

    I like DSB's
    A lot easier and cheaper to set up than other methods.

    Make a skinny return line, like the skinny overflow. Do not need to be that wide, glass level equal to overflow level. With sides 5 mm longer anf a small glass piece across the top, like a roof. So you have a slot where the water exit on exactly same heiht as the water exiting over the overflow.
    Position should be so that water that enters system should not impact the overflow.

    in short run the return line to the bottom of the tank and have outlets below the rockstructure. drill an anti syphon hole just below the water level to stop the tank from being drained in the evnt of a power outage.

    I'm going with 2 x 50mm return. My current tank has 50mm return and its lovely!

    can you explain how the reverse flow works?

    might just do that...

    Can you explain what you mean by a roof across the top?

    nope the water pumps to the bottom the anti syphon hole is there to suck air in and cause the syphon to stop should the power go out.

    Sentari, IMO the return is all but insignificant ....... my thoughts are that it simply is there to return about 4x the tanks volume an hour ... in anything other that a softy reef or a seahorse this flow is basically insignificant. but then thats just my little 2c worth
