help with closed loop A friend has purchased a 180 gallon tank with 4 - 1 1/2" holes in the back all same size and layed out geometrically i am trying to draw but using notepad so the spacing isnt correct in the drawing but it is on the tank I am trying to get suggestions on how to run the piping for the loop and should i use spraybars or what on the inside also what should be on the return side thise will be run by a little giant pump also a little over 1000gph
thank you for the help

I'd draw from the bottom holes. The Pump should be in middle between the holes so that equal draw comes from both. few turns as possible for the life of the pump and for efficiency.

So maybe a t something like this.

Ahh, it didn't work. What I'm trying to say is to put a T junchtion between the two intakes. Then go down to the pump. do the same coming back up from the closed loop.
