Have a 150gal. tank with a 40gal. sump. Will be using the current 3150gph. Will 2 1in return lines be sufficient with a 2in drain?

That will be close to limit of a 2" drain. Are you planning a Herbie or Beananimal style or just a single drain? Aren't current pumps DC, i.e. controllable?

Just regular single drain. Yes current pumps are controllable. Thanks
