The Fluval E Series are one of the most technically advanced submersible aquarium heaters available, the VueTech LCD display delivers peace of mind by continuosly showing the real time water temperatures. The temperature display changes colour if the aquarium water temperature varies from the required level. The screen is green when the temperature is correct to the level initially set, if the aquarium drops by three degrees the large screen becomes blue and should it rise by the same amount the screen becomes red, still showing the accurate temperature. Fluctuations to this level are usual in natural conditions but any more can be harmful and these heaters are the ideal monitor ensuring that even rises in temperature caused by an outside source are monitored and notified.
The initial setting level is accurate to half a degree. The integrated fish guard offers advanced protection for fish and invertebrates. The 100 watt model is suitable for aquariums up to 120 litres.
