filter making a lot of noise ~ help!
i am using two emperor 400 filters in my tank... one of them was making a lot of noise... like grinding noise...
i removed that filter, fit the parts back tightly and plugged in it... after it finished pushing all the air out, the filter worked for 3 minutes and started that grinding noise again...
i removed the propellers from both filters and inter changed them...
this filter became quiet and the other one started making all the noise...
