in my 370G I have a hammer head return split into 3. 2 wavey seas and regular lockline on the 3rd. The hammer head also feeds my chiller that returns to the sump and a 30G frag tank that also returns to the sump.
I use a Ocean Motion 4way on a closed loop drived also by another hammer head pump. There are 12 outputs to the closed loop that have on off functions depending on the OM 4way
