I have a Penguin 350 and Rena XP3 filter on my 55 Gal. Recently I took the the Penguin 350 apart and cleaned it as lots of dust from the crushed coral had collected. Once I cleaned it and put everything together it was working fine but there is lots of noise from the motor. Did I mess something up? I tried taking out the intake pushing it back in but it didn't help. I've had this filter for 3 years and never had any problems, cause I guess I never took it apart. How can I fix it? Please help me out. Thanks!
Also, would only XP 3 filter be enough for 55 gal aquarium?
