Adding multiple 3/4" returns to increase flow rate

[ilikefish69]

if you want similar flow go from 1" to two 1/2 "

So I added a third line, printed a little Y connector and have three 3/4” lines coming out of the single 1” PVC return line. That was definitely the missing piece, I am now at a higher gph than I ever have been. It seems like in this hobby once we get something how we like it, we must continue to tinker. I’m sure there’ll be a 4th and a 5th and a second return pump in the mix in the near future… thanks for all the help everyone!
