Sitting here wide awake crunching numbers, flowrates, and head loss! 29dt 20sump What flowrate do I want going through sump? My flow rate in the dt is over 10x. I’m talking about the flowrate going through the sump to facilitate the best filtration? I’m thinking 29g times 5= 145gph? Or 29dt +20gsump=50 times 5=250gpg? Return will be 4 feet head, with a three pipe manifold for GFO, Carbon, and future use. Please help?
