Practical guide
Aquarium emergency checklist: leaks, outages and equipment failure
A short plan for reducing damage and preserving oxygenation.
Safety first
During a leak or flood, disconnect power only when it can be done safely. Do not touch wet electrical equipment.
Biological priorities
During a power outage, gas exchange, temperature and filter-media condition become priorities. Reduce feeding and observe livestock.
Record emergency equipment
Keep a journal list of backup aeration, containers, towels, device details and battery replacement dates.
Important: Adapt actions to the species, equipment instructions and actual measurements. For signs of illness, consult a veterinarian experienced with aquatic animals.
