How do you calculate the size of the return pump,
I have a 100 gallon with a 30 gal. Sump,
Would the Eflux Dc pump 1050 gpm. Be strong enough and reliable for this set up? Please advise, thanks

In general we throw around 3 to 10x display volume after head loss for the GPH (gallons per hour)..

So for a 100G tank a 300GPH to 1000GPH rated (after headloss..see pumps chart) return pump is fine..
I go 10x or more even personally..

And you wrote 1050GPM (gallons per minute).. Typo I'm sure..

Nice thing about DC pumps is that you can adjust them and plan on extra should you ever want to run reactors,etc.. off the return pump..

Pump specifications have 210 to 1050 gph you are right I wrote gpm , I think I can get a deal from Amazon on this model . Thanks
My first option was the jebao dc 1200 but I hear wat too many complaints about this pump not being reliable, thank you ,

No one really knows if the Eflux pumps are going to be reliable either as they really haven't been out long enough either..

I personally am using a Jebao DCP-6500 pump on my 80G tank w/40b sump without any problems.. But I've only had it for a few months..

Prior to that I had a Jebao DC12000 running on my 120G tank for 3+ years without a single issue.. It was never cleaned either and never missed a beat.. The DC series is not as quite as the DCP series..
