Aquael Glass Heater 100W Platinium Heater Water Conditioner 25055C CARBON CARTRIDGE 2PK 55CConventional glass heaters for aquariums basically consist of a thermostat, thermostat contacts, and a heating coil. The thermostat controls the water temperature in the tank and, when necessary, switches the heating coil on or off by connecting or disconnecting the contacts. Thermostat contacts constitute the weakest link of this system. Although their operation is electronically assisted, metal oxidation gradually causes their surface to corrode.
