How To Read The Temperature Bar In The Aquarium?


Keeping fish healthy in an aquarium is no easy task. You must keep your tank clean, make sure it has the right salinity, make sure your fish have enough food (though not too much), maintain the right PH levels, and keep it at the right temperature. While there are many thermometers to choose from for fish tanks, adhesive, stick thermometer strips are the cheapest and easiest to use, although they may not be easy to read.

Installing tank temperature stickers is easy. Thermometers can be installed on the side, front or back of the tank (preferably without blocking your view of the fish in the tank), but you must clean this area first. Wipe the outside of the tank with a glass cleaner and a soft, fleece free cloth. Next, strip the adhesive from the thermometer strip and attach the strip to the glass without touching it to make sure it is straight. When the bar is straight, press it against the glass. Finally, use the side of the credit card to flatten out the bubbles under the sticker. According to the Fish Tank Club, stickers should be ready to use about 30 minutes after installation.

It may be easy to install an aquarium thermometer sticker, but how do you read it?  These thermometers usually have Fahrenheit on one side and Celsius on the other.  While some thermometer bars work like traditional mercury thermometers with a red line down the middle, most have a rainbow of colors and move up and down depending on the temperature, giving you a temperature range.

The blue/purple part of the rainbow reflects a temperature lower than the actual temperature of the tank. Red/orange indicates temperatures higher than the actual temperature. The actual temperature of the sink is about the middle of the rainbow, usually in the green zone. For example, if blue and purple are 84 degrees, green is 86 degrees, and red is 90 degrees, then the temperature is probably closest to 86 degrees.
