An aquarium heater is necessary for all of your aquatic pets since they are used to certain temperatures Trusted Source Aquarium Temperature Control A good aquarium temperature range is 76° to 80°F (25° to 27°C). A reliable heater is necessary for most tropical fishes. www.tfhmagazine.com in the wild. In fact, most tropical or saltwater fish prefer warmer temperatures, so keeping the water between 75 and 80 degrees Fahrenheit will ensure that they will thrive. Even the normal temperature of our home is too cold for them, plus there are seasonal temperature changes that cool things down in the winter or require the use of air conditioners in the summer. A heater will maintain the water’s temperature for more comfortable conditions for any fish or reptiles you keep.
If you’re going to have an aquarium in your home, you need to stock it with fish that can handle the temperatures you set Trusted Source Selecting a pet fish Pets are an important part of the American household. Your pet-owning experience will be most enjoyable if you carefully consider which pet best suits your family, home and lifestyle. Unfulfilled expectations are a leading cause of pet relinquishment, so make an informed decision. Take time, involve your family, and give careful consideration to the following questions. www.avma.org . Not all fish like the same conditions, so you need to choose carefully. For instance, there are several cold-water fish species, like Bloodfin Tetras and Endler’s Livebearer with wide temperature ranges of 65 to 82 degrees Fahrenheit. The Odessa Barbs and Celestial Perl Danios prefer things a bit more stable, between 73 and 79 degrees F. Tropical species like Molly fish prefer things a bit warmer, so keeping your tank between 75 and 85 degrees F is a must.
Installing an aquarium heater can vary from model to model, though most of them include similar steps. Attach the suction cups or other mounting pieces to the heater. Then place the heater at the back or side of the tank, pressing the suction cups into the glass for a firm hold.
Be sure there is an outlet nearby to plug the heater into. Some models can be placed vertically or horizontally, so you can position them however they fit best to avoid the substrate and other tank items.
Leave the heater in the water to adjust to the temperature before plugging it in. Once it has been acclimatized, plug it in, set the temperature you want for the tank if possible, and turn it on.
For the safest heater, choose one made of durable materials to avoid cracking or damage if it gets knocked by the aquatic life in the tank. Be sure the heater is as submerged as instructed to avoid damage to the device. Place it near the filter to ensure the proper water circulation for the most accurate temperature possible.
If you’re unsure what to look for in a new aquarium heater, the following sections can help determine what you need.
There are two main types of aquarium heaters, including substrate and submersible heaters. The substrate models are best for reptiles and plants, so we didn’t include these in our reviews. Submersible models are designed to be used underwater, so are great for all species of fish, as well as turtles, snails, and other water dwellers.
The best 25-watt heater for aquariums obviously isn’t as powerful as a 200-watt model, so the lower-powered models are best for smaller tanks. If you need more power for a huge aquarium, you can choose models like the hygger Fast Heating Titanium Aquarium Heater. You can also use two heaters in a single large tank for more even heat distribution if necessary.
The tank capacity is something else to consider when choosing a new aquarium heater. The larger the tank, the more powerful the heater needs to be, so you won`t be able to use a 50-watt heater for a 300-gallon tank. The more water the tank holds, the more powerful the heater needs to be for the most efficient heating possible.
Some aquarium heaters, like the Aqueon Preset Heater, have a preset temperature, so all you need to do is install it in the tank and plug it in. Other models have a range of temperature options, like the Cobalt Aquatics Neo-Therm Pro. This allows you to adjust the temperature as needed for the aquatic pets in the aquarium and the conditions of your home. The wider the temperature range, the more options you have on the fish you can keep.
Many of the aquarium heaters on the market include some safety features. One to look for is an automatic shut-off when the water level drops below the acceptable level for the heater or when it starts to overheat. Some heaters are made of glass, so shatter-proof material is a must to prevent a broken heater. The Tetra HT Submersible Aquarium Heater also has a shock-resistant exterior for even more protection.
Most of the models in our reviews have some sort of indicator, which is designed to show you when the aquarium heater is running and when it has shut off, usually due to the proper temperature being reached in the tank. This can be a simple indicator light or a more elaborate one, like the one on the Fluval E300 that is green for safe temperatures, blue for too cold, and red for too hot.
The durability of the heater you use in your aquarium determines how long it will last and how safe it is. The stronger the material, the longer it will last and the less chance there is that it could harm your aquatic pets.
A good warranty will cover any issues your heater may have. Though a 1 or 2-year warranty is fine, the Marineland Precision Heater offers a lifetime warranty, so you won`t have to pay to replace a faulty heater.
Heaters come in varying sizes, so you also need to look at this when choosing one for your tank. If it doesn`t fit well in the tank because it sticks out the top or takes up too much space, it won`t be usable. Check the dimensions of the tank and the positioning options for the heater before choosing one.
Not everyone has an outlet right next to their aquarium, so a longer cord is best. If it is too short, it won`t reach, requiring the use of an extension cord or new placement for your aquarium.
With so many aquarium heaters available, it can be hard to choose one. To help you decide, we have a few favorites we`d recommend.
Our top choice is the Fluval E300, which is a 300-watt model designed for tanks up to 100 gallons. This model is fully submersible, with a wide temperature range and dual sensors for accurate readings. This heater also includes an LED screen with a color-coded display.
