Do aquarium heaters contain mercury?
I have an Aquarium Heater in my fish tank and I would like to know whether aquarium heater's contain any mercury within them.
Modern aquarium heaters do not use mercury - the switching mechanism is a bimetalic bar which curls one way when hot - and switches off the heater, and curls the other way when cold and switches on the heater. These movements are very small and well calibrated. No mercury is used.
