I moved the tank outside to do leak test. I will let it sit for 3-4 days.

Did a little work today.

Was thinking of doing the return in 1" pipe with a spry bar in the tank. What do yall think. why or why not with 1" return. Overflow is 1" pipe.

A spray bar would put a lot of backpressure on your return pump. So would using 1" pipe. That would require a stronger pump, which means more heat and more power consumption. What is it you are trying to achieve with these measures? Also, a spray bar would do nothing to contribute to water movement in the display tank.

I will use a return pump around 1000gph. Spray bar would run by the sand to keep it clean. Just a idea.

Okay, so your spray bar is located just above the substrate. That means your return is totally submerged. What happens when the pump is turned off? - instant back siphon! Your whole display tank is sucked dry, your sump is overwhelmed and the floor is flooded. Not what you intended, I'd guess.

Was going to use a flapper valve to stop the water if the pump turns off. My lfs has one that has no metal parts in it. I would put two in line in case one failed.

Off to a good start...I have a 180G but mine is only 5' long

On the back-check (flapper) valves, make sure you get the type with the transparent body so you can see if the flap is closing all the way. They are notorious for failing at the worst times, so make sure they are removable/replaceable in your set-up.
