Greetings all, recently i noticed that my fx5 has had extremely low amount of water flow coming out of the hose. it sounds perfectly normal and i doubt any air has gone in. this happened a couple weeks back and i assumed that maybe cleaning out the filter would help and it seemed to work up until now. the flows gone back to its low rate and i wondering if its time i change the impeller and motor since its been quite a while since i’ve last done that. problem being that i cant really find spare parts for the discontinued fluval fx5, and i dont know if fx6 parts work on my old fx5. please let me know
