Digi-temp (Battery Included) External Thermometer Round-the-clock temperature display Mounting suction cups and battery included; long temperature probe cord Amazingly compact and lightweight

Digital Thermometer

The Digi-temp (Battery Included) External Thermometer is composed of two distinct components: 1. Sensor probe - It sits underwater in your fish tank and is able to monitor the temperature. The probe is able to be moved to any place inside the tank. 2. Digital display remains out of the water and displays the temperature of your tank. It also contains a battery. The reason behind this split design is Water and electricity aren't compatible. If you keep the probe and display in separate locations the essential electrical parts aren't soaked. If you're looking for an instrument that doesn't stay in your aquarium for long periods of time then this is the ideal option. Simply attach the probe to the tank as required to monitor the temperature, and remove it after you're finished. The probe is separate and is connected to it by a wire cord. This permits you to place the probe permanently inside your tank while the meter rests on the outside and displays the temperature of the tank. Benefits:
  • Reliable
  • Sturdy
  • Easy-to-read
  • It won't take up too much of the aquarium space.
  • The probe is easily moved to any area within the aquarium

Why Thermometers are Important

Aquarium thermometers are a tiny but crucial item to have in your aquarium. While your tank might appear nice, an abrupt change in temperatures can cause harm to both plants and fish. Using a thermometer to monitor your water's temperature at different times and on different days can aid in identifying and fixing issues caused by temperature fluctuations. View all thermometers

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
