CHEZURAquarium decisions Lifting a full internal filter can release its entire captured load. A container around it keeps that waste together.
Stop flow before air enters. Catch drain water and dispose appropriately.
Rinse foam for passage and retain part of any colonised cartridge rather than wholesale disposal.
Remove grit from rotor and shaft, inspect housing, clean or replace cups.
Confirm immersion and that return direction remains animal-safe.
| Situation | What to do | Why |
|---|---|---|
| Sludge spills out | Use submerged container | Captures the load |
| Mounts slip | Clean or replace | Prevents vibration |
| Rotor scrapes | Check grit and shaft | Restores rotation |
After use submerged container, measure or observe Sludge spills out again with the same method. Record Inspect cable and mounts too. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
