    is the pump to be used from a sump to tank to "pump" water up..
    or will it be to recirculate water inside the tank ? ( to create current )

    for sump to tank: a mag7 or mag950 is perfect. put two if you wish to have redundancy if one stalls or breaks up.

    for recirc, all depends how much you are willing to spend and the type of look you want to achieve. you could have your tank drilled and use external pumps with an oceans motion device.. or you could add vortec pumps or just a bunch of maxijets on a wavemaker. Spray bar or directional nozzles..the sky's the limit.. the list goes on and on.

    all depends on what you want to spend and the look you want.

    let us know.

    planning next tank, possibly 60x30x20 on 2x plasma.

    as liv has pointed out, there is a difference between flow through a sump and flow in the tank.

    the recommended flow though a sump is 3x - 5x tank volume, you can go higher if your sump can handle it.

    flow for a tank is usually..

    FOWLR 20x tank volume
    softies 30x tank volume
    SPS 40x+ tank volume


    is your tank drilled? if yes what size holes??

    what size sump are you using??

    OK thanks for the quick replys, My tanks is drilled has one 2 1/4" bulk head, now I want to have as little as possible in the tank when it comes to powerheads, I find they are eye soars, but if need be I'll add one or two, I would like to have two return lines or just one split into two to get more water movement in the tank, now do I need the sump to have a line fed into to it for movement in there? Im going with a 36x18x18 sump with live rock bits and refug. in the sump, with a sand bed. I think Im doing it right, Ive ran fluidized beds on freshwater for years and it put bio-balls to shame and just wated to know if this can be used?

    Thanks PAZE

    ya.. forget bioballs.
    as for the tank,
    i'd run two seperate lines to the sump ( for safety, not for extra flow ) run a 2 small pumps to bring sump water up )

    then for circulation, you can drill one more hole to take water and use a spray bar with those directional nozzles. or go the vortec way. I agree on teh powerheads.. not my personal choice as well.

    if you go spray bar, check for a oceans motions 4way, and feed the spray bar with it as well as a few other jets.

    choices are endless.. search around and look at our tanks for what you like.
    all depends what kind of look and the budget u got.

    if money is no object.. get 4 vortec and dont look back. but they are expensive @ ~350 a piece. but no holes, no drips, tons of flow and very quiet.

    From the other thread, I dont want to use crushed coral if I can get away with it, I wanted sand, but was told it was to hard to mantain, also with sand can I get away with just 1-2"? I dont want to use bio-balls if I can get away with it, is there a better substitute like live roch bits?

    sand or aragonite are both great.
    you do not use underwater plenums like freshwater.
    sand on the bottom of tank.. then add rocks.
    some people go barebottom and have their sand on another part of the system.. refugium etc..

    I personally like the look of sand and aragonite...also.. most people wont recommand a DSB in the main tank.. its better to have it seperately so it can be taken offline if needed and cleaned / restored.
    so ya. 2" is just fine in the main tank.

    Extra hole for safety in what way, will the single bulk head not handel the water flow? and could you direct me to the vortec site or where I can see this set up?

    safety for if that single hole gets clogged up real nice one day due to fish/starfish/cucumber/snails etc getting in there or wrapping themselfs around the opening.. I had a lynkia that did that.. evil creature. he he.. i'm sure it knew I had one drain anyways.. I always recommend 2 holes from now on.

    for the vortech.. check it out
    http://www.ecotechmarine.com/products/mp40w.php

    they are wireless and communicate to each other.. real nice stuff.
    also check them out on youtube.

    You wouldn't need 4 of those vortech's.. 2 would be plenty.
