Aqua One ThermoSafe 200w Aquarium Heater - Twin Pack

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. This is a twin pack of 200w heaters for those who prefer two smaller heaters in a larger set up. Will heat up to 400l
