Suitable for Marine and Tropical aquariums
The Hydor ETH In-Line External Heater is designed for vertical use with most aquarium applications involving water hose of the specified diameter.The ETH must be used in a vertical manner for correct operation. The most common application is for use with canister filters, however the ETH is easily adapted for use in almost any situation where heated aquarium water is required, such as with wet/dry sump pumps. The ETH is easily installed by cutting the tubing and connecting the two parts of the tube to each side of the ETH. For reduced maintenance, it is recommended that the ETH be installed within the filter's output assembly. As most canister filters are not designed to bear weight, it is recommended that the ETH be properly supported by the use of the attached loop to avoid stress on the output assembly.

The ETH heats with high efficiency by means of an internal heat pump system that avoids temperature variations.Fits most canister filters such as the Hydor Prime with the use of a short section of tubing to complete the connection.
