How to Select a Fish Tank Heater

A Guide to buying a fish tank heater. A fish tank heater is just one of the many things available to help you to imitate the natural environment that your fish would live in if they were in the wild.

Selecting the Fish Tank Heater

While the more inexpensive fish tank heaters may look more inviting when you look at the price tag, keep in mind that these are more likely to have issues in the future and end up costing you more money in the end. Some of the common problems experienced with the cheaper fish tank heaters are less than accurate temperatures, breaking, or other types of malfunctioning.

Accuracy is one of the most important features of a fish tank heater. Most of the fish tank heaters in the middle price range are very accurate and will maintain a constant temperature with very few adjustments. These are the better investment when it comes to fish tank heaters because they last longer and in the end you spend less money total on them.

Fish Tank Heater Monitoring

In order to help you monitor the temperature in your tank and be able to keep an eye on how well your fish tank heater is working, you will need a good thermometer. This is another area where you don't want to take the cheap way out.

The cheaper thermometers, like the cheaper fish tank heaters, are not always accurate and can malfunction. An aquatic style thermostat is also necessary so that your fish tank heater can turn on and off as necessary to keep the water temperature constant.

There are three different types of fish tank heaters available for purchase. The fist, the Thermo Heater, is an all in one heater and filter. This is convenient because it allows the water to be filtered and heated simultaneously. The second type, the Rod-type, is attached to the back of the tank and is either submerged or not.The user manual can inform you better on how to use this type because it all depends on the brand you purchase as to whether or not you can put it under the water.

Lastly, the bottom heater, uses heating cables that are put down before the gravel or other substrate that you use in your tank. These fish tank heaters are put to good use in aquariums that have plants, but are a little on the expensive side.

There are several options as to what type of fish tank heater you want to use with your tank. The bottom line is that if you purchase one of the more inexpensive models you will likely pay for it in the end by spending more money than if you get one of the models in the middle price range. Think it through and do some research before you purchase your fish tank heater. Know ahead of time what features you are looking for. This should help you when you set out to purchase a fish tank heater.
