Water Movement

[TRIX]

Hey All
My tank has the return located in the very middle of the tank. My thoughts are to bring the pvc right up to the top to a T then out to either sides. My question is would it be better to put another T on each side then a 2 45's to create flow everywhere or should I just put on a 45 and try to make the water flow in a swril in the tank. I also have 2 SEIO 620 to help.

I'm having good luck with a spray bar made from black 3/4" irrigation pipe from home depot. You could run it out to both sides from a barbed tee, cap the two ends, and put the holes at any angle you want to adjust the flow.
It gives great flow down and out under your rock to clean out the crap and then use your Seio's for circulation.
