Feature
ENSURE YOUR BETTA FISH GROW AND THRIVE --- It is absolutely essential that your aquaria should be heated between 75 and 77F for optimal comfort and metabolic efficiency of your betta fish. Any temperature below 70F will cause your bettas to enter a state of minimal activity and they will be stressed and miserable. Make sure Betta are at their optimal health and performance with this heater.FULLY SUBMERSIBLE 100% WATERPROOF HEATER--- This 10-watt aquarium heater supports 1.5 gallons (5 liters) fish tank. Its exterior is designed with tougher than glass and the sealed polymer can be submerged into your tank. The heating element is surrounded by a thick plastic to ensure 100% protection of your fish. It is also explosion-proof, Shatterproof, durable and has an anti-scald surface. It has a non-corrosive shell for strength which makes it nearly indestructible.
AUTOMATICALLY REACHES THE PERFECT PRESET TEMPERATURE --- The smart Betta heater by SunGrow has a built-in electronic thermostat to automatically maintain water around 75F which is ideal for most tropical fish. It saves you from the trouble of constantly keeping a check on the temperature of your tank. It will automatically shut down when it will reach around the desired temperature, no manual adjustment is needed. This ensures that the temperature is not too high for your fish.
CREATES THE IDEAL CONDITIONS FOR YOUR BETTA FISH --- Betta are tropical fish. That means they need warmer water to live in. This heater will create the ideal conditions for your betta fish to thrive in. The warm water will keep your betta fish calm and happy and make their metabolic process efficient. A few preconditions are required to allow it to run with maximum efficiency. The heater must be completely submerged in the water and the indoor temperature should be 62-75Fahrenheit
INCLUDES SUCTION CUPS FOR EASY INSTALLATION ---- Easily install the SunGrow Betta Heater vertically or horizontally by using the built-in suction cups to attach to your tank. The best location to place the heater is in the stream of a powerhead or near the water flow, such as the outlet (or inlet) from the filter.

Description
What size tank is this SunGrow Aquarium heater used for?The size of the water heater is 13.5*2.5*1.7 inches. This has enough power to heat up max 3.5-gallon tanks. If you have a bigger tank consider using a different SunGrow aquarium heater. The heater runs between 8-13 W. You can easily install it against the aquarium window.
Why is a fully submersible heater better than half submersible?
The fully submersible heater gives the aquarium hobbyist more freedom to place the heater wherever they prefer in the tank. Each aquarist will decide on the ideal placement of the heater. The heat will circulate due to the flow of water from your filter. Ideally, your filter will thoroughly mix the water to prevent any torrid or cold zones creating a calm and tranquil habitat for your betta fish.
How will this heater help with energy conservation?
This heater has a very efficient heating module, which can transfer the electrical energy into heat energy at a rate that is 20% higher than the traditional heating rods. It is more resilient than traditional glass sleeve heaters.
How safe is this for my betta fish?
The heating rod is 100% safe to be submerged in your fish tank. The extra strength engineered plastic keeps your fish away from the heating element and prevents any exposure or collision with the actual heat source. It also has an Auto Shut-Off feature. So if the aquarium is overheated, it shuts off automatically and resets when it cools down.
