Precision Temperature Control for a Healthy AquariumTetra has reinvented aquarium water treatment by designing an extremely accurate heater that installs inside the power filter.Engineered for optimum efficiency and safety, the heater is now isolated from the aquarium, while actively heating all of the water as it cycles through the filter.This active heating system is more efficient than the passive heating provided by traditional heaters because all of the water in the aquarium is actually forced into contact with the heating capsule.The Tetratec Heating CapsuleIntegrates inside your Tetratec Power Filter.Temperature Control Knob puts temperature adjustment outside of the aquarium at your fingertips.Electronic Thermostat for increased accuracy and reliability.Over-heat Protection insures safe operation even when the filter is dry.Shatter Resistant Glass for increased safety and durability.
