i am trying to plan the plumbing for my 65 gal tank. the return pump that i have is the jabao dcp 5000. for the tank drain, i will be using 1 1/4 inch pipe, but for the return, i would like to split that return from 1 to 2 so that i can have my returns be one on each end with the overflow being in the middle of the two. i am hoping that someone has any suggestions on tubing/pvc diameter. i feel that if i have 1 1/4 from the return pump, and then spit it into 2 seperate 1 1/4, there isnt going to be enough backpressure to properly move water.
would it be best to have it maybe be a smaller diameter, such as a 1" all the way up, or 1" to the split, and then run 3/4 to the ends? or, would it even matter? i dont want to run the pump at 100% just to move water, and want to make the pump as efficient as possible, but at the same time, dont want to strangle it.
