Closed loop pump???

In my 125H I only have one overflow and one return. I am planning to add a closed loop pump for added circulation. Please let me know what you think of this set up.
Start with 1" suction line from top of tank down to a Velocity T3 mounted under the tank. The 1" line will have to be necked down to 3/4" MPT to fit the pump. I think that I will use 3/4" pvc on the pressure side back up top to a spray bar. The T3 is for about 700 GPH with this head height. The spray bar will be 3/4" with 4 1/2" adjustable spray nozzles.
thanks

Your setup sound fine to me...........as far as priming goes I've never had to prime my closed loop, it would be a pain if I had to though :)

That's what I was thinking. From what I can find it alternates water flow side to side. My question is all of the SCWD pictures I have seen they are all set in the same position. Will the SCWD run on its side or upsidedown?
