Features
🔧 5 ADJUSTABLE TEMPERATURE SETTINGS (72℉–94℉) - Customize the ideal water temperature for your betta or tropical fish tank. Easy-to-use button control with five settings: 78℉, 82℉, 86℉, 90℉, and 94℉—more flexible than standard preset aquarium heaters.
🔌 82.6" EXTRA-LONG POWER CORD FOR EASY PLACEMEN - Say goodbye to outlet struggles. The extended 82.6-inch cable provides greater flexibility for positioning in 5 to 15-gallon fish tanks—even in complex or hard-to-reach setups.
🔥 DURABLE NICKEL-CHROMIUM HEATING ELEMENT - Heats quickly and evenly for efficient performance. Designed to outlast typical aquarium heaters—perfect for everyday use or as a reliable backup.
🐠 EXPLOSION-PROOF & LEAK-PROOF CONSTRUCTION - Fully submersible design with sealed, anti-crack housing to help prevent electric shock, leaks, or damage. Safe and worry-free for small aquarium owners.
⚠️ IMPORTANT SAFETY REMINDER - Do not bury the heater in sand or substrate. Keep at least 2 inches of clearance from the water surface. Always ensure the heater is fully submerged before plugging it in. Unplug the heater and let it cool for 10–20 minutes before removing it from the tank for cleaning or water changes.
💕 RELIABLE AFTER-SALES TEAM - Worry-free purchase with full support throughout your fishkeeping journey. Fast resolution for shipping damage, setup issues, or part failures within 48 hours.
