An Aquarium Temperature controller will give you peace of mind knowing your fishy friends are safe and comfortable. This blog will discuss why a temperature controller is essential and mention some aquarium heaters. We all know fish thrive at a specific temperature, and we want to maintain that temperature.
Before investigating strategies to adjust an aquarium's temperature, it's necessary to know the appropriate temperature. Most tank fish thrive at 75-80 degrees Fahrenheit (23-27 degrees Celsius), but some require warmer water. If your Tank only has one or two varieties of fish, research their optimal temperature range and keep it there.
In an Aquarium hobby, heaters have temperature sensors to maintain the desired temperature; however, a heater is an electrical component that can fail. So, we do not want to discuss the result when the heaters fail. However, a heater can fail by not working anymore- not producing any more heat drop in your Tank, so this situation also has the same sad result.
We'd like to mention KaveMan Aquatics briefly; on his channels, he gave a bunch of knowledge about the aquarium hobby; in his approach, a temperature controller can be used as a safety measure using redundancy.
So Let's look at some approaches
We take an example of a 75-gallon tank; in this circumstance, a 300-Watt heater will be sufficient to heat the entire Tank. So you can get two 200-watt heaters instead of one 300-Watt heater. These two 200-Watt heaters work together to keep the Tank's desired temperature. You may ask what you have accomplished with that; we can say if one of those smaller heaters malfunctions and stay stuck in one position, it will not be powerful to overheat your Tank as the temperature rises from a malfunctioning heater. This situation will buy you some time the notice the correct problem.
The next level of safety is to add a temperature controller. Again, there is a specific way to set this up to give you all three safety features. So, with this setup, you want one heater (300-Watt) to be powerful enough to heat your entire Tank alone. Then you want your second heater to be smaller(200-Watt). We aim to set up all three to back up each other and act as a safety measure.
So you connect the 300-Watt heater to the temperature controller and leave the smaller one as a standalone heater. The 300-Watt heater will be set at a temperature slightly higher than your controller. Therefore, the standalone 200-Watt smaller heater sets a temperature lower than your controller. Let's have a look deeply at the system. In this setup, the temperature controller will be the master temperature sensor. When the water temperature drops the below the setting on the temperature controller, the controller will trigger the main heater(300-Watt) to turn on.
So probably, you'd like to ask, what if the temperature controller fails? If the temperature rises heater sensor will acknowledge the higher temperature, and the heater will shut itself off. In case both the temperature controller and the main heater fail, there is no need to panic because, as you remember, the standalone heater is a backup in the system. When the temperature drops, the small heater will kick on. (We set the temperature below the temperature controller). Also, if the small heater fails and stays stuck in the position, it is too small and won't ever be able to overheat your Tank.
