    Mag Drive 18 for my 60g tank too much?

    I bought a mag 18 today for my 30g sump to my 60g tank. Is it too much flow?

    I was hoping its enough flow to eliminate my two maxijet 1200's.

    This will pump water up 6ft then go thru a scwd wavemaker, then to my tank.

    there was too much flow when I used a mag 7 going up 4 feet in a 75 gallon with a 30 gallon sump. Might be a little too much. But then again the sqid will take allot too. ?? I guess the best way to find out is to try it.
    Cheers,

    yes.. the squid will take alot of power..
    you can also just throttle it using a valve.

    i think you should seperate both process.

    so have some kind of recirculation or pumps for circulation
    and have a different pump for the sump.

    you could Tee it to a skimmer, that'll reduce the flow significantly, and u wouldnt need to put a pump on the skimmer

    Interesting idea. hyeah:

    I was thinking about putting a valve and I could control the flow that way. I guess its better to have too much flow and throttle it back as required.

    I dont want a smaller pump because I will probably upgrade to a bigger tank in the future.

    Will my two overflow's be able to keep up? They are 2.5" drilled with 1.5" fittings.

    hopefully your overflow can take the gallonage coming out of that return pump and back to the tank

    Yeah

    I will have to throttle the presure back with a valve if not.

    i have a mag 9.5 in my sump going to my 72 bow from and its tee'd off to my refuge and i find i have to throttle it back a fair amount to match my overflow from my reef ready overflow, although i dont have as long a distance/head to pump up to

    best of luck with your set up. be sure to post some pictures!

    I bought the 9.5 a few days ago and exchanged it for the 18 today because I did not calculate the loss @ 6ft.

    I will definately post pics when everything is done.
