Your limit will be the 1.5" drain hole. I asked and asked when I set my tank up and could not find a definitive answer. There are just to many variables. I'm going to doubt you can push 1950GPH through 1.5 " you could always "T" off the return and have it go back to the sump. Or use it to drive a skimmer, Chiller, or Frag tank.
