Aquarium Thermometers

One of the most basic and yet vital parameters the aquarist is charged with maintaining is the temperature.

All kinds of monitoring equipment is available that is designed to provide quick and accurate measurements. Whether you choose digital or alcohol based thermometers, place them where the animals are, and avoid costly inaccuracies resulting from areas with poor flow.

Also, never trust a digital thermometer completely, always reference it against a basic thermometer to ensure it is output is within reason.
