Frequently Asked Questions
Q: How Many Gallons Can Aquarium 50 Watt Heater Warm Up?
A: As a rule, such models can heat up to 15 gallons of water.
Q: How Long Does It Take For A Top Fin 50 Watt Aquarium Heater To Warm Up?
A: It depends on the initial water temperature and aquarium size. In aquariums up to 10-15 gallons, the heater warms water by 1°F/hour – it’s a safe rate for keeping fish not stressed.
Q: Top Fin Aquarium Heater 50 Watt How To Set Temperature?
A: It depends on the model – some of them come with a dial, while others feature buttons and display for easy temperature control. In Top Fin Aquarium Heater, you should find the knob on the side and turn it looking at the dial – you will see the red bar moving correspondingly. Set the red bar on the needed temperature level. Now when it works, its red indicator will be on, and it will automatically stop when the required temperature is achieved.
Q: How can I keep my fish tank warm without a heater?
A: An aquarium heater is an essential piece of equipment, especially if you keep tropical fish. However, sometimes, you may need to keep your aquarium without a heater for some time. For example, it may happen in the case of a power outage. Your primary task will be to retain the existing temperature. Use a thick blanket or a towel to wrap the aquarium around. If you have electricity, use aquarium lights to heat the water. If possible, try to raise the room temperature or use any other heat sources available. As a last resort, prepare several containers with warm pure water and add it gradually to the tank.
Q: Can you have the cord of the submersible in the water and is it safe?
A: Submersible heaters for aquariums are designed to be completely immersed in the water. As long as the cord of the heater is not damaged, there is nothing to worry about submerging it in the water. These are quite effective tools. They must be placed quite low in the water to distribute the heat evenly in the water. Even though you can position your submersible tank heater horizontally, vertically, or even at an angle, the best position is horizontal if it comes with a thermostat. Just be cautious to keep the heater off the gravel. Otherwise, the tank glass will crack, and a fire hazard will arise.

Do I need to consistently check my heater?
HI,
The majority of aquarium heaters these days come with thermostats, which prevent overheating. Once the required water temperature is reached, a heater switches off automatically. Thanks to that, temperature fluctuations are minimal. However, to make sure your heater is functioning correctly you can measure the temperature in your aquarium with a separate thermometer once a day.
Cobalt Neo Therm Submersible Heater has a sleek, modern design with a ‘one touch’ control system. This submersible electronic heater has an advanced thermostat that is accurate within 0.5F. It has an easily readable LED display that displays the tank temperature and set the temperature simultaneously. The heater can be set up to 96F. As a safety precaution, the integrated thermal protection circuitry shuts down heater automatically when it overheats. The heater has a shatter proof casing which makes it almost indestructible. This heater is ideal for fresh water and salt water aquariums.
An aquarium heater is made of a few components. The sensor is able to determine the water temperature that surrounds it and will signal this to the thermostat. The thermostat component marks the desired minimum and maximum temperature levels and will activate and deactivate the heating element to keep the water within the desired range.
