WATER CIRCULATING: Both functions can be used independently. During warmer months, can turn off the heater and use only the water circulating to enhance water flow, promoting oxygen exchange, which benefits fish and plant health. It also reduces sediment buildup, keeping the environment clean
VERSION 2.0 UPGRADE: Upgrade the impeller water pump to enhance water flow performance. The water pump function increases water flow, forms a water circulation, preventing stagnant areas and improving water quality. Even heat distribution is achieved as the water flow helps disperse heat, avoiding localized overheating
QUIET UPGRADED DESIGN: This enhanced aquarium heater now operates significantly quieter. A thicker casing blocks internal motor noise, softer larger suction cups reduce tank vibration. And increased water pump lifespan, changed internal materials
EXTERNAL CONTROLLER PRECISE TEMPERATURE CONTROL: Features a clear 3-digit LED display that shows real-time and set temperatures, making it easy to adjust and monitor water temperature. Ideal for freshwater and saltwater fish, ensuring the water temperature remains stable within the set range
