Tank / Sump plumbing

[PNWReefer17]

OK...looking for a little constructive criticism here. First time plumbing a tank and sump. Does anyone see any glaring issues here aside from the missing 90° fitting coming off my return pump? I appreciate any and all feedback. Thanks!

The one overflow pipe is pretty long. If that is a full siphon, it might 'air-lock', which will prevent the siphon from restarting when the power cycles.

Also, did you take into account the siphon that will form from the return pump when it gets shut off? i.e. the sump can handle the amount of water in the pipes (all four of them), as well as what the return line will suck back in.

Which overflow pipe are you talking about? From left to right on the overflow box is main...emergency...secondary.

The left most one.

I would also add pipe hangers for all four pipes applied towards the top of the stand OR use wood attached to the top back side of the stand that now contacts the four pipes and use PVC conduit clamps.

The return in the center of the tank is likely to get little flow. They would if they were equal length.

It may not be what you are going for but I am putting it out there.
