Unlike basic heaters, its preset calibration minimizes temperature fluctuations, creating a stable environment that supports vibrant fish health. The compact design ensures it integrates seamlessly into smaller tanks, providing essential warmth without compromising aesthetics or space. For Indian aquarists, this means a healthier habitat for your aquatic pets, especially during cooler months or in air-conditioned rooms. **Who It's For & Who Should Skip** — This heater is perfect for owners of small Betta tanks (3-5.5 gallons) or other tropical fish setups requiring a steady 78°F. It's ideal for those seeking a simple, plug-and-play solution without complex thermostat adjustments. However, if your tank is larger than 5.5 gallons, or if your ambient room temperature frequently drops below 60°F, you will need a more powerful heater. Additionally, this unit is preset and not adjustable, so if you require precise temperature control outside of 78°F, consider a different model. ## How to use 1. Ensure your aquarium is between 3 to 5.5 gallons. Confirm you have a voltage transformer (110V to 230V) and an appropriate plug adapter for India's power supply. Check the heater for any damage before proceeding. — Prepare for Installation 2. Completely submerge the AQUANEAT heater in the aquarium water. Use the included suction cup to securely attach it to the glass, either horizontally or vertically, in an area with good water circulation. — Submerge and Mount 3. Plug the heater into the voltage transformer, then into the Indian power outlet. The indicator light will turn red when heating. Once the water reaches 78°F, the light will turn green. Use the included thermometer sticker to verify temperature. — Connect Power and Monitor 4. Always unplug the heater and wait at least 10 minutes before performing water changes or removing it. Never touch the heater while it is powered on. Do not bury it under sand or attempt to disassemble it. — Maintenance and Safety ## Product details | Field | Value | |---|---| | Instructions | Fully submerge heater before plugging in.

For small tanks from 3 to 5.5 gallons, a 25W heater like this AQUANEAT model is suitable. A general guideline is about 1 watt per litre of water. For larger tanks or colder rooms, you may need a higher wattage heater. Always check the product's recommended tank size range. ### Will this aquarium heater work on Indian mains power? This AQUANEAT heater is rated for 110/60Hz voltage. India uses 230V/50Hz. You will need a step-down voltage transformer to use this heater safely and effectively in India.

Ensure the heater is fully submerged in water before plugging it into a compatible 110V outlet (via transformer in India).

The indicator light will show when it's heating. ### What is the preset temperature and is it adjustable? This AQUANEAT heater is preset to 78°F (25.5°C), which is ideal for Betta and most tropical fish.

The heater is designed to be safe for both freshwater and saltwater aquariums, providing stable warmth to support your fish's health. ### How do I check if the heater is working correctly?
