Pump for return dead

So my pump in my sump that does the return to my display tank is dead. It was a rio 1290gph at 1". Now I just have a 650gph @1" that is pumping into my chiller back into tank. It looks like it will be a couple of days before I can get the pump replaced. It was recommended to move my power heads higher up in my tank and if need be place the heater in the tank as well. Any other recommendations or just ride it out...thanks

 

I think you are going to be fine. That's a lot of head for a smaller pump but it isn't going to be the end of the world.
