Mag 9 pump

[rockman]

I have a mag 9 pump as a main on my 75g saltwater reef it's been in service for about a year and a half now. Lately I've noticed deminished flow rate.I've check the rest of the system for obstructions My question is could this be a worn impeller? would buying a new impeller help or is it a waste of time? should I get a new pump and be done with it?

Thank you for your time
