i use two dct 15000s for 480g at speed 1 and 3. one of them divert half of the water to a 110g and 70g.
Mayne i should get the dct 15000. I wanna be able to run these pumps on the lower end of the spectrum.
Im going with 1.5 inch drains maybe the 15000 would be a little to much since your on setting 1. Thanks man2in drain, 3/4in returns.
I too don't like to run my DC pumps for return and CLS at full throttle. Mainly because I dont have the need at this time for my filtration and circulation, respectively. Another added benefit is knowing i have more headroom and not pushing the pumps.
Are there other reasons you want to run ~43% at the third setting?
I would see any reason not running a canister off the sump for other chemical use. I made one section of my sump so water travels in a narrower section so I can put chemical media like carbon, crush coral, and etc... keep it simple like everyone here says... View attachment 1222699
