CHEZURAquarium decisions Priming fills the circuit so the pump moves water rather than air. The correct method is design-specific.
Check tank level, seal, lid, valves, hose and submerged intake. Pre-fill HOB or vessel where required.
Never mouth-siphon aquarium water; use the equipment’s safe method.
Air noise should decline. If cavitation persists, stop and find the entry rather than waiting minutes.
Verify leaks, flow and short outage restart; keep the procedure nearby.
| Situation | What to do | Why |
|---|---|---|
| Motor hums dry | Disconnect immediately | Prevents heat damage |
| Bubbles persist | Find air-side leak | Circuit is not closed |
| Prime lost while off | Inspect valves and level | Air enters or water drains |
After disconnect immediately, measure or observe Motor hums dry again with the same method. Record Tilt or shake only when instructed. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
