Aqua One ThermoSafe 50w 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 50w heater for aqauriums of up to 50l. If your aquarium is situated in a cold location go to the next heater model up.
