Maintain precise, stable water temperatures in your sump or filter box without taking up valuable tank space using this external Sunsun heater.
- You set target heat levels between 20 and 35 degrees Celsius on the clear LCD panel, removing temperature fluctuations that stress your livestock.
- You protect against dry-fire damage because the heating chamber shuts off instantly the moment it senses interrupted water circulation.
- You secure the 300-watt or 500-watt body to your filter outlet by aligning the flow arrow with current direction and attaching the provided 16 mm or 20 mm hose adapters.
- You ensure reliable operation across different regions by replacing the socket cover with the included UK, US, EU, or AU converter rated for 110-120 V and 220-240 V mains power.
