Closed loop system design

[outdrsyguy1]

Could use a little input on my closed loop set up please.
I'm using a reeflo hammerhead and eductors for flow in the closed loop. I'm hoping to buy either a 3-way valve or 2 two way vales to oscillate flow to set up a gyre in each direction. So one side would turn on, then 5 minutes later the other would turn on while the first closed off. I haven't figured out where to put the closed loop return line or the tank supply line coming back from the sump. Here's a couple quick sketches I threw together to try and figure things out.

One thing I would say is, I think you might need to move those holes inward a bit, the holes that close to the edge of the glass and that much water weight may cause the glass to fracture.
Look at motions ocean for the water movement.

The tank will be 1" acrylic but I get you. I'll look at better places to bring them in

Do people ever put filters or strainers on the return?

I know some put sock on their return but only when doing cleaning, not on a permanent basis.
sorry my last post should have been oceans motions wavemaker.

I keep a filter sock on my return and change it about every 3 days.
