This Swell Thermometer Strip is a great way to monitor the temperature inside your aquarium. Thanks to its sticky back, you can quickly and easily attach it to an outside surface of your aquarium.

It’s recommended that you place it in an area that’s easily visible so that you can keep an eye on any potential temperature fluctuations happening inside your aquarium.

With its wide temperature range from 18-34C, or 64-93F, this Swell Thermometer Strip is suitable for many different kinds of aquariums, particularly tropical ones where maintaining a stable temperature is important for the health of tropical fish.
