Description
xMeet HITOP's compact submersible heater, designed for flexible setups from a 1-gallon betta bowl to larger 70-gallon tanks. Available in 25W, 50W, 100W, 200W, and 300W, this heater pairs a simple external controller with a durable, fish-friendly body. The 68–93°F adjustment range fits a wide range of freshwater and marine environments, offering steady warmth without dominating your tank's silhouette.
Smart control at your fingertips
The external controller sits outside the tank with a 5.6 ft cable, letting you adjust the temperature without reaching into the water. The digital LED display shows both the set temperature and the real-time water temperature, so you can monitor at a glance. A clear heating indicator on the controller makes its status easy to read even from across the room.
Small size, big versatility
Despite its compact footprint, this heater covers a broad range of small to mid-size tanks. It’s suitable for seawater and freshwater, and is well-suited for betta enclosures, turtle tanks, and other compact habitats where a discreet heater helps maintain a stable environment.
Crafted for longevity and safety
The heater uses thickened quartz glass and a robust seal to minimize water ingress while providing reliable heat. The design aims to stay protected in active aquariums and busy setups. It’s easy to install with included suction cups, base cover, and a thermometer sticker so you can monitor conditions at a glance.
