Return pump speed and sump water level question

[Waxhaw reefer]

Not sure if this helps, my 55gaklin tank with an eshopps over flow rated at 600 gph, I had an ehiem rated for 562 full open, now I have a jebeo dc6000 on the third setting putting out more and also running a gfo/carbon reactor , as far as flow threw the sump, it out what u want threw it, might want slower flow so that skimmer or refuge will pick up more, I always adjust mine for noise even if it's slower, flow in the tank is the crucial one not the sump, don't worry about all that times crap!!!

So slower is better in the sump? I know I can add powerheads in the DT for flow.

Yes look back at my first post in this thread, I talk about just that.

Headloss is the vertical distance from the sump water level to the display level measured in feet of head. Then you would add an additional foot or two for all the fittings and friction losses in the piping. 5-6 feet of headloss is pretty normal. Look at your pump curve and see where 5 or 6 feet of head puts your flow.

Depending on the volume of water in your sump you may want to keep the return flow at around 3-5x the display volume so you don't have microbubble issues in the display. It is cheaper energy wise to make up the bulk of your turnover in the display with wavemakers/powerheads which only draw a couple watts each and give you a more random flow than a return. The lower return flow also makes your in sump protein skimmer more efficient as it has more time to process organics with a lower velocity through the sump chambers.

Smart man. I have my simplicity3200 return pump for my 60gallon at lowest setting. Anything more brings microbubbles into the display. I move the rest with two Jebaos, and may add another gyre.
