Step-by-step response
1 week before: Test parametersVerify ammonia/nitrite at 0, nitrate under 30 ppm, equipment running normally. Fix any issues NOW.
5 days before: Do a water change30% water change with parameter-matched RODI. Resets nitrate baseline + dilutes any accumulated waste.
3 days before: Clean equipmentReplace mechanical filter floss, wipe powerhead intakes. Clean equipment runs more reliably while you're away.
1 day before: Set up auto-feeder (if needed)4+ day trips: program Eheim Twin or Petlibro to dispense small portions every 1-2 days. Test 3 consecutive feedings before leaving.
Day of departure: Final checksTop off ATO reservoir to max. Check heater + powerheads. Trim long plants away from filter intakes. Take a photo of tank for reference.
During vacation: Optional check-inTrip 7+ days: have a neighbor verify equipment running. Send tank photo to compare. Apex/Hydros remote alerts cover most emergencies automatically.
Return: Test before feedingCheck parameters BEFORE first feeding. If ammonia spiked, do a 25% water change first. Resume normal feeding gradually.
FAQ
Can fish survive a week without food?
Yes. Healthy adult fish in a mature tank survive 7-10 days without feeding with no harm. Some species (oscars, large cichlids) tolerate 14+ days. Stop feeding for 1 day before vacation to clear waste.
Should I use an auto-feeder?
For 4+ day trips: yes, but program SMALL portions every 1-2 days (not daily). Auto-feeders that over-dose cause ammonia spikes worse than fasting.
Should I shut off the lights?
Reduce photoperiod to 6 hours. Total darkness stresses some fish; sustained lighting promotes algae while you're away.
