Aquarium Thermometers

Modern aquarium heaters have built in temperature settings, showing what temperature they are set at. Even with this nice feature available on a heater, it is still very important to monitor the actual temperature of the aquarium with a thermometer. Digital aquarium thermometers and more traditional mechanical aquarium thermometers are both very common in the fish hobby. The digital thermometer has an advantage of being quicker and easier to read, and is located outside of the aquarium. Traditional thermometers are less expensive, but are more difficult to read accurately.
