    Default Filter inlet and outlet positions on a 125

    0 Not allowed!
    Building my first tank (125 gal) and I'm about to install two Eheim canister filters w/ corresponding inlets and outlets. Filters themselves will be located below in the stand.

    What I'm wondering is what are the best positions for the inlets and outlets for optimal water circulation.

    My plan is to position a spray bar (outlet) at the far left side of the tank at the surface pointing to the right, and the corresponding inlet in the middle of the tank extending straight down to just above the substrate layer. Then right next to that inlet will be the second canister's spray bar positioned in the middle of the tank near the surface pointing right, and then that filter's inlet will be on the far right side of the tank in the corner again extended down to just above the substrate.

    Does this sound ok for an inlet/outlet setup or is there a better arrangement I should consider?

    In my experience what's best is to have one on each side of the tank. One spraybar is mounted on the side glass pushing the water across the length of the tank towards the other tanks intake, which is in the other corner. The second spraybar is mounted vertically on the back glass and pushes the water back along the back of the tank towards the first filters intake which is in the other corner.

    One same as what you said with one change have one intake higher than the other.

    Or put the returns on each end pointing to the center and the intakes in the middle. And use a high and low depth set up.

    Oh how would you support the spray bar in the middle of the tank?
