Aqueon Pro Aquarium Heaters are some of the most popular heaters available on the market for freshwater and saltwater aquariums. They’re sought after due to their tough build and durability. They come in five different sizes, which provide a different output of wattage. The smallest of these heaters will warm aquariums up to 20 gallons, and the largest will warm your fish tank up to 100 gallons. This article will dive deeper into each model, and I intend to provide the specs, dimensions, and many other features of these heaters. Before I jump into the details of each model, I will discuss some features that each heater shares.
Adjustable Heat Setting Dial
Each Aqueon Pro Heater comes included with a dial at the top that allows you to adjust the temperature to your needs. For this heater model, you can adjust the heating setting from 68°F to 88°F. From fish that tolerate cool water like Zebra Danios to fish that need incredibly warm water like the Discus Fish, this heater model will cover your bases.
Shatterproof Build, Fully Submersible, & Auto Shut-Off
This is a shatterproof aquarium heater because it is not made out of the glass like many others. Also, because of the material used for the build, the heater itself is nearly indestructible. It can take a beating from large fish such as Oscars. The Aqueon Pro Heater Series is also fully submersible. This allows you to put it into your fish tank at different angles to hide it behind decorations, plants, or rockwork. However, do not tilt the heater top below the bottom. This will cause the heater to shut off for what I assume are safety reasons.
The Aqueon Pro Heater has a nice feature that forces it to auto-shutoff when it overheats. It’s a nice safety feature that will help protect your aquarium from cooking if the heater were to fault out. As an extra bit of protection, I do recommend purchasing a temperature controller, like the Inkbird Aquarium Probe Thermostat. The controller has an over-temperature sensor with a fault alarm, which should help prevent a fish tank from overheating.
Aqueon Pro 50
The Aqueon Pro 50 Submersible Aquarium Heater is the first and smallest of the series. It is rated for fish tanks up to 20 gallons and uses 50 watts of electricity. This heater measures 1.5″ x 1.75″ x 9″. Ideally it will be great for 10 gallon, 15 gallon, or 20 gallon aquariums. You may need a smaller heater for 5 gallon fish tanks. You can buy the Aqueon Pro 50 watt Heater on Amazon by clicking the link, or you can find this heater in other online shops or at your local fish store.
Aqueon Pro 100
The Aqueon Pro 100 Heater is slightly larger than the Pro 50 in size and wattage. This is a 100 watt aquarium heater and is rated for fish tanks up to 40 gallons. It also measures to be 1.5″ x 1.75″ x 10.5″. This heater is 1.5″ longer than the previous model in this series. The Aqueon Pro 100 Submersible Aquarium Heater is a fantastic choice for 29-gallon, 30-gallon, and 40-gallon aquariums. You can check this heater out at Amazon by following the link.
Aqueon Pro 150
The next jump up is to the Aqueon Pro 150 Submersible Aquarium Heater. This model uses 150 watts to warm your fish tank water and measures 1.5″ x 1.75″ x 12.75″. It is recommended to be used for aquariums that are up to 55 gallons. I would even recommend using this heater for 40- or 30-gallon aquariums. This is only if you can comfortably fit it into the fish tank. Take a look at this heater on Amazon by following the link above!
Aqueon Pro 200
The Aqueon Pro 200 Heater is the second largest model in this series of submersible heaters. It uses 200 watts to warm your aquarium and measures 1.5″ x 1.75″ x 12.75″. It shares the same measurement as the Aqueon Pro 150 but has a little more power than the previous model. This heater is rated for fish tanks up to 75 gallons. Consider picking up one of these at Amazon by clicking on the link above.
Aqueon Pro 300
The final and largest heater in this series is the Aqueon Pro 300 Submersible Aquarium Heater. This behemoth of a heater will use 300 watts of electricity and measures 1.5″ x 1.75″ x 15″. It is also rated to warm aquariums up to 100 gallons. It should also do incredibly well warming 75 gallon and 90 gallon fish tanks. Don’t forget to pick this one up on Amazon by following the link.
