The rena filstar I have is about 3 years old.After I clean and do a water change, it pumps really well, then slows to a trickle after a few days.Is it the rota or does it need replacing?

A:After three years there could be one main factor or several factors combined which can cause this issue. We have outlined many of these factors in earlier Q&A's already posted. Here are some links to those sections:
