• A practical and accurate water thermometer that attaches to a water pipe and does not get in the way in the aquarium.
• Easy to install: insert the battery and attach to the flexible hose (e.g., from the aquarium filter) using the spring clip.
• A sensitive temperature probe on the back of the thermometer measures the temperature of the aquarium water via the temperature of the tube, which is the same as that of the water.
• Suitable for all pipes and hose types from 12 to 26 mm in diameter. Also suitable for silicone hoses. Preset alarm for water temperature below 18°C ​​and above 28°C.
• Contents: 1 digital aquarium tube thermometer and 1 LR1130 battery. Dimensions: 5.0 x 3.5 x 1.8 cm

Water temperature in aquariums is crucial for both animals and plants, so it's essential to monitor it carefully. Most tropical ornamental fish thrive in water between 24 and 26°C. However, some fish prefer cooler temperatures. Discus, from the cichlid family, are among the fish that find slightly warmer temperatures, between 27 and 29°C, ideal. Axolotls and many freshwater shrimp, on the other hand, prefer cooler water. Water temperature can be raised using submersible heaters (such as the JBL PROTEMP s or JBL PROTEMP e) and lowered using chillers (such as the JBL Cooler).
