Pump Rate for Closed Loop ?

[minsmarine]

I am DIYing closed loop with SCWD.

Pump will be external and about 1.8M below water surface. Inlet is from UG. And thinking about Resun brand as I already have resun SP6000 for my sump ( quite reliable so far and no noise for my case ).

I am just wondering, should I get resun King series or still SP series. Has anyone tried out before for closed loop ?

Appreciate your guys ideas.

Hi Bro,

I'm planning to have SCDW on my return also. Using eheim 1262 with head loss of about 3.8. I should be able to get at least ard 700 - 800gph flow rate to the SCWD. Since SCWD will cost a drop of 20% flow rate, my actual return flow rate should be ard 560 - 640gph.
