AGA overflow and return pump

    90 gallon AGA drilled tank- I did not purchase the AGA overflow system but
    ordered a Durso standpipe instead.
    My question regards the return line.

    The 1" overflow will give me 600 GPH into the sump, right?
    Is this enough for a 90 gallon? I don't want to limit what I can keep in
    this tank.
    Is there any reason I cannot use the 3/4" return hole for a drain line as
    well?
    How much more GPH would that give me and will it work?

    I never understood why they put the return line right next to the overflow-
    seems it would function better if the return line entered the tank further
    away from the drain?? If I used both the predrilled holes for overflow I
    could route the return anywhere into the tank that I want it and get
    (presumably) more thorough circulation??
    (I will probably do a totally separate closed loop system later on, but am
    just working on the initial system now.)

    Also I intend to install one SCWD in my return, and don't know which
    submersible pump I want- Mag 9.5 or Mag 12??
    Is there a better choice?

    (and if I am wrong or confused on any issue please correct me now!!)

  2. You want your sump running around 3x - 4x total volume of the display tank.
    Using the 3/4" return line will permit you to put a couple of "locline" outlets
    pointed toward the other end of the tank. The water will naturally flow back to
    the draining overflow box.

    A Mag 12 will work fine with the SCWD, because the unit can handle up to
    1400gph. Just remember that you'll lose 20% of the flow your Mag pump is
    creating. That is quite a bit when you include the head pressure of pushing
    water up 4'-5' high.

    Better to have the SCWD on a closed loop, if possible, and a Mag 9.5 or 12 for
    your sump's return pump.

    That is what I have decided to do- better now in the design phase than six
    months down the road facing a redo.
    Thanks again for your patience.

    Your planted tank is lovely, really especially nice. I look forward to
    seeing what you do with a reef tank.

    Gee... thanks!
    I kinda wonder how it will turn out as well.

    Research phase is winding down- not that it will ever be over, but the
    actual ordering of items means I have made a decision or two. Products and
    opinions change so frequently that committing to various brands is scary.
