where to find pvc for return line?

Just about any home improvement or hardware store. The Mag 5 has a 1/2 inch male pipe thread output on it. Now what I would do is get a 1/2 in female pipe thread to 1 inch slip bushing, then a 1 inch slip/slip coupler then use 1 inch PVC pipe to go up to the tank (you will need a few elbows depending on how your plumbing is arranged.

I'd throw a union in there to make it easy to get the pump out for maintenance.

David, the HD in Regency Square will have everything you need. The Ace Hardware on University right at 95 will also have everything you need. I don't remember where the nearest Lowes is to you but there is one on Phillips Highway ust south of Baymeadows Rd. Any of them will let you take the pump in with you. Then you KNOW what fittings will fit it and what won't. Of the three, I like HD the best because they seem to have a better organization to where you find the fittings. HD sorts them by size, Lowes by type and I have never seen a rhyme/reason to Ace other than "Plumbings over there --->".

No ball valve needed. This is an internal pump (I'm assuming). Water will drain down to sump level on power outage anyway.

A ball valve is used to control the amount of flow, not to prevent water from draining back in the event of a power outage. That would be a check valve.

DUH - Yes, IF you buy a pump that is over rated for the flow that you need to your tank, THEN you will need a ball valve.
BUT since we are only talking about a Mag 5 with 500 gph AT BEST and a heck of a lot lower once plumbing is installed, I doubt that a ball valve will be necessary to restrict the flow on the pump.
IF this Mag 5 is the return pump for your 125 gal (from your signature) - I'd reconsider the pump. You'll need something bigger IMO.
Don't even think about check valves. Check valves = waste of money as they WILL fail at some point. Better to design your system without them in the first place.

A ball valve is needed for various maintenance scenarios. Some day you will wish one was there

IF all the mag 5 is doing is sending water to the display tank and no where else then I see NO reason for a ball valve UNLESS you want less than about 400 gph going into your tank (I'm taking 100 gph off for plumbing).
You DO NOT need a ball valve to remove it for maintenance. All the water in the line will drain into the sump on power outage. A union is all that is needed to remove the pump for any kind of maintenance.
Unless there is some unknown reason that you would need to restrict the output of the pump (or this pump will be external) I will still stand on NO REASON at all for a ball valve. It would be a waste of money.
Aquaman: Please tell me even one of the "various" reasons why you would need a ball valve in this particular situation.

But in this case, turning a ball valve closed, would not result in any less water in the sump. That's my whole point as to why the ball valve IS pointless.

Oh geez. I see your point now. IF, and I repeat IF, your sump is overfilled (which it shouldn't be) then turning the ball valve FIRST before you turn off the juice WOULD save the water in that one pipe from going into the sump.
Now - let's talk reality. The amount of water that you would save would be very minimal. It would probably be about a 4 foot piece of 1" PVC. How much water is that? And if that much water means a flood or no flood then you have a lot more serious issues with your system.
