I just installed a 750 gph pump on my baitwell tank and I am not sure it is pumping to full potential. When doing the math, that pump should pump 12.5 gpm (minute) and when I pump out my tank it takes like 5-7 minutes with only 25 gallons in it! Is there a possibility of incorrect wiring (backwards) or is it just the way the pumps are? I was hoping for a hard stream out my spray nozzle (look at picture) to make the tank water spin real nice, maybe I need a smaller diameter outlet to add more pressure to the system.:confused2: Also there is about 11 ft of hose before exiting over the side of the boat, I know that effects pump pressure.
