When keeping fish, it is very important to check the water temperature. If the water temperature suddenly changes without your knowledge, and the fish become weak, you will be in trouble...! This time, we will introduce a water thermometer that can be installed easily and easily.

Where should the temperature gauge be placed in the aquarium? Here, an example of an aquarium using a general circulation filter is explained.
Install it as far away from heaters and fans as possible.
the water temperature gauge Installed as far away from heaters and fans as possiblewill do. The water near the heater is warmer than elsewhere, and a water temperature gauge placed there will read a higher than actual water temperature.
In the case of a fan, installing it at the intake port of the filter will give a more accurate value.
A place that is easy to check and does not disturb the layout is even better.
As long as the above conditions are met, you are free to choose the location, but I think many people place it in the corner so that they can see the creatures in the aquarium better. It doesn't make sense to put it in a hard-to-see place.
Place it in a location that is easy for you to find so that you can easily check it.
Water temperature gauge types and features
Even if it is a water thermometer, when you go to a pet shop, there are many types and you may not know which one to choose.
Water temperature gauges are roughly divided into two types, analog water temperature gauges and digital water temperature gauges, but basically there is not much difference in performance.
analog water temperature gauge
The analog water thermometer features a simple shape like an old-fashioned thermometer. Since the analog water temperature gauge does not require batteries, it can be used semi-permanently.
On the other hand, it has the disadvantages that the numerical value is difficult to read, the accurate water temperature is difficult to understand, and the water temperature range is narrow, about 0 to 40 degrees Celsius.
digital water temperature gauge
The digital water temperature gauge is designed to display the water temperature measured by the sensor on the monitor screen. The advantage of a digital thermometer is that it is easy to read. The feature is that you can see the water temperature at a glance.
Another advantage of a digital water thermometer is that it can measure temperatures over a wide range, from -50 to 110°C. On the other hand, since it runs on batteries, you will need to replace the batteries. Also, since it is an electronic product, it may break down if it gets wet.
