Frequently Asked Questions

When choosing a submersible aquarium heater, look for one that is adjustable and easy to install. Many models have a temperature setting and timer, so you can make sure the water stays at an ideal temperature. You'll also want to make sure it fits your tank size. Some popular brands include Tetra and Aqueon.

Submersible heaters should be placed near the bottom of the aquarium, away from any decorations or obstacles. Make sure to keep the heater away from the sides and the top of the aquarium to ensure that the heat is distributed evenly around the tank.

Submersible aquarium heaters use electrical coils to warm the water in your tank. The heat is then circulated through the tank via convection currents. As the heater warms up, it also changes the density of the water, making it lighter and creating a natural circulation pattern.
