Hi all, my Fluval 206 canister filter has developed an annoying rattle over the past few months. Can anyone advise?
- Weekly clean of impeller, housing and shaft
- Monthly grease of impeller using silicone grease
- I always lock the intake/outflow pipes when cleaning to prevent air getting in the system, I then move the filter around a little when running again to dislodge any air bubbles (if extremely noisy)
