This heater provides that consistent warmth, ensuring your Betta thrives. Unlike ambient room temperature fluctuations which can affect fish, this device actively regulates water temperature, offering a reliable solution for small tanks. **Who Should Use This Heater** — Ideal for owners of small Betta tanks (3-5.5 gallons) or nano aquariums needing a reliable 78°F preset. It's perfect for beginners due to its plug-and-play simplicity. Those with larger tanks or requiring precise temperature control beyond 78°F should consider higher wattage or adjustable models. Ensure your room ambient temperature doesn't drop below 60°F, as this unit is designed for supplemental heating. ## How to use 1. Ensure your aquarium is filled with water to the appropriate level for the heater. Confirm your room ambient temperature is above 60°F (15.5°C) and that you have a compatible 110V voltage converter and plug adapter for India's 230V mains. — Prepare Heater and Tank 2. Fully submerge the AQUANEAT heater in the water. Use the included strong suction cup to securely attach it to the tank glass, either horizontally or vertically, in an area with good water circulation. — Submerge and Mount Heater 3. Plug the heater into your voltage converter and then into the power outlet. The indicator light will turn red when heating and green when resting, showing it's maintaining the 78°F preset temperature. — Connect Power and Monitor 4. Always unplug the heater and wait at least 10 minutes before performing water changes or removing it from the aquarium.
