I need something cost effective and quiet, external...hmmm) Also I have minimal room from the bulkhead to the pump in the curved stand so I have a 90 degree off the sump(not ideal, I know)but not sure there is anything I can do about it...Is it worth replacing the PS4 if I can't eliminate the 90? Pic shows the 90 off the sump. Pump is just right off that 90 and then the return comes straight up from the pump. My returns have those 90 bends too because we tried to work with the plumbing that came with the tank.

Check this for me Carmen;
Using a flash light look in the water for bubbles after your last baffle and before your pump. check to see if you are getting any bubbles cascading from your last baffle. Another thing is fill up your return area in your sump level with the last baffle turn off your pump for a few a seconds and plug it back in( try to get rid of any bubbles in your lines) and check your tank after a few hours.
