Emergency response

How to prepare your aquarium for a hurricane / storm

Step-by-step response

7 days before: Stockpile suppliesBattery air pumps (1 per 50g), spare batteries (D-cell, 6+), RODI water (40 gallons), salt mix, food, dechlorinator, test kits.

3 days before: Top off + testTop off ATO. Test all parameters. Do a 30% water change to baseline. Resolve any equipment issues NOW.

24 hours before: Final prepMove tank away from windows. Tighten lid clamps (jumpers escape during outages). Charge phone battery banks. Locate aquarium-grade backup heater.

During storm: Run on backupsBattery air pumps for oxygen. Generator if available (run heater + powerhead). Don't open the tank lid - retains heat + moisture.

Storm passes: InspectCheck structural integrity of room/house. Test tank parameters. Watch for leaks from wall vibration.

Post-storm: Bio-filter recoveryTest ammonia + nitrite every 6 hours for 48 hours. Bio-filter may have died from extended outage. Don't feed for 24-48 hours. Slow recovery.

FAQ

Can my aquarium survive a hurricane?

Yes with prep: battery air pumps + generator for tanks 100g+ + stockpiled food + water. Coastal zones with frequent outages typically install standby generators.

Should I move my fish during a hurricane?

Generally no - tank failure is rarer than transport injury. Exception: if hurricane track shows direct hit + you have time to evacuate, transport in coolers with battery air.

Aquarium-keeping fundamentals

Whatever specific topic brought you here, four fundamentals govern long-term aquarium success: water quality, parameter stability, biological filtration, and species-appropriate husbandry. Skip any one and the others struggle to compensate.

Water quality: ammonia + nitrite at zero, nitrate under 30 ppm freshwater + 10 ppm reef. Test weekly with API or Salifert kits. Use our water parameter checker to score your readings against your tank type.

Parameter stability: stable wrong parameters beat fluctuating ideal parameters. Most fish tolerate a wide pH range if it's stable. Sudden swings of 0.4+ pH or 5+°F kill fish faster than chronic suboptimal values. Use temperature controllers (Inkbird) + automated dosing for consistency.

Biological filtration: the bacterial colony on your filter media + rock + substrate is the engine. Never replace all media at once. Use our filter turnover calculator to size correctly.

Species-appropriate husbandry: research adult size, territoriality, diet, and tankmate compatibility before purchase. Use our tank stocking calculator + compatibility guides.

Frequently asked questions

How long does an aquarium take to set up? 4-6 weeks for full cycling + first stocking. Use our cycle ETA calculator + how long does cycling take.

What's the best aquarium for beginners? 20-gallon long. Big enough for parameter stability, small enough for budget + space. See beginner picks.

How often should I do water changes? 25-30% weekly. See water change frequency Q&A + water change calculator.

Why does my fish keep dying? 5 leading causes: uncycled tank, wrong species pairings, no quarantine, undersized tank, neglected water-change schedule. See full diagnosis.
