• LCD displays actual water temperature. This display provides peace of mind as the actual water temperature is continuously displayed in either Celsius or Fahrenheit.
  
• High/low temperature alert. During normal operation the temperature readout will change color if the aquarium water varies +/-1C (+/-2 F) or more from the pre-set temperature. If the temperature is too high the LCD will become red and if too low the LCD will become blue.
  
• Precise and easy temperature adjustments. With the easy to use adjustment lever the temperature can be precisely set in 0.5 degree increments.
  
• Advanced fish protection. the integrated fish guard keeps fish and invertebrates from coming into direct contact with the heater core. the heater is protected against shocks from large fish species.
• Mounting Bracket. The heater bracket easily clips on or off the slim line mounting bracket or can be vertically adjusted for precise placement. The included adapter provides the option of side glass mounting when traditional rear glass mounting is not possible.
