Aquamanta Efx200

Hey guy and gals
Sorry if this is already been covered but new to forum and unsure.
I have a 170ltr tank and currently running a aquamanta efx200 external filter. I’ve had the filter for nearly two years and have noticed a significant decrease in flow but not in cleaning. Filters have recently been changed and impeller has been replaced due to broken shaft. Does anyone have any suggestions or ideas as to help improve.
Thanks

 

Welcome to Fishlore.
I’m not familiar with that filter, hopefully members who are will be able to help you today.

 

Can you provide a link to the model filter you have?

 

This is the filter it’s only Maidenhead aquatics own brand

There it is

 

Have you tried cleaning out the lines there could be buildup inside there causing a lower flow... or where the impeller is there could be buildup u can usually clean it out with a skewer or a qtip
