Aqua One ThermoSafe 300w Aquarium Heater

The quartz glass and microchip temperature control on Aqua One's new Themosafe heaters makes them virtually shatter proof in normal use and they even switch off if removed from the water while still connected to the electicity supply. Excellent where toughness and good temperature regulation are required. We suggest the Thermosafe 300w heater for aqauriums of up to 300l.
