JBL Aquarium Thermometer DigiScan Alarm

The water temperature in aquariums is of crucial importance for animals and plants and must be monitored. Most tropical ornamental fish feel most comfortable at temperatures between 24 and 26 °C. However, there are also fish that prefer lower temperatures. The discus is one of the fish that find higher temperatures between 27 and 29 °C to be ideal. Axolotls and many freshwater shrimps prefer cooler temperatures.
The water temperature can be raised with the help of heater thermostats (JBL PROTEMP s or JBL PROTEMP e) and lowered with the help of coolers (JBL Cooler).
