Inline Aquarium Heater for Stable, Clutter-Free Temperature Control in Planted and Freshwater Tanks

Keep your planted or freshwater aquarium at a stable temperature without placing another piece of equipment inside the display. This high-precision inline aquarium heater connects directly to the outflow tubing of an external canister filter, supporting efficient, even heating while preserving a clean aquascape.

Choose between 12/16 mm and 16/22 mm tubing sizes to suit a compatible external-filter setup. Both versions share the same compact dimensions, voltage range, power range, and cable length.

Key Features

• Inline placement moves the heater out of the display tank, leaving more visual space for fish, plants, and carefully arranged aquascaping.
• Installation on the external canister filter’s outflow tubing distributes heat throughout the system, supporting stable and even water temperatures.
• Compatibility with planted and freshwater aquariums makes this a practical temperature-control option for established external-filter setups.
• Two tubing-size variants let you match the heater more closely to standard aquarium tubing rather than adapting a single fixed connection.
• Listed filter compatibility makes selection clearer: the 12/16 mm model suits UNS Delta 30, Delta 60, Delta 90, and Blitz 32 oz filters, while the 16/22 mm model suits the UNS Delta 120.
