Eclipse L overflow placement

[fishguy1978]

I ordered an Eshopps Eclipse L overflow for the 260g. I realize I will need to eventually add a second one as they are only rated to 150g. The tank measures L= 84in (213cm), W= 30in (76cm), H= 24in (61cm). I am trying to decide placement of the overflows. I could do one on each end panel or equal spaced on the back panel.

Are you deadset on this overflow? Maybe try one of the larger boxes from fijicube or modular marine?

I'm all about simplicity with my builds, so I would use a single larger box mounted center on the back panel, returns mounted on the left and right.

Otherwise, I would put the 2x eclipse L boxes on the back centered at 30" and 54", and drill 3/4" returns at 12" and 72", then a single 1" return at 42" (perhaps split to smaller nozzles to split flow).

That's a sweet tank, excited to see how it turns out.

Thank you. It's a giant guppy tank at the moment.
I have the eclipse in hand. I had a credit at lfs from selling fish and was not aware of the other brands.
I brain farted on the width being 30in. I could put both overflows on one end.
I will do some layout though to see what looks right.

Hmm, I like the Fijicube but I like the idea of dual overflows too.

What sump setup are you using?

Sea clear wet/dry but I am already thinking about how to add more.

Yeah maybe 2x of those, one for each overflow. If you did that, I would change my above plan. Forget the center return, squeeze the boxes in towards the middle of the tank a bit, then have a single 1" return on either end of the tank. So essentially youd have the overflow boxes right over the drains of each wet dry, and the returns right over the pump sections. This way you don't have pipes and lines running all over the place and each sump is identical so you can balance the flow through each easily. Just my thoughts, there are definitely other ways to handle it.

For me......Flow is often determined by the type of fish kept.
At the moment I keep riverine/ rheophillic species, so in order to best replicate a riverine habitat, I put overflows on one end, with a 1500gph influent (water entering from the sump) on the other end, so currents flow along the entire length of the tank.
I also use an 800gph powerhead to accentuate flow down the same length for more rheophillic species.

For lacustrine species, an overflow on each end might better imitate natural habitat.

For those species (tigerish, etc) that appreciate counter current, I might use 2 powerful powerheads aimed to clash to create that type zone, mid tank, along with multiple points of entry from .
