Description
xOverview
The SEAOURA 800W aquarium heater is designed to support warmth in large tanks from 100 to 180 gallons. Its submersible design keeps the heating element fully immersed, while a temperature probe wire runs to the heating rod to monitor temperature across multiple zones. An external controller lets you set the target temperature with ease, and suction cups secure both the heater and the probe to prevent drift during daily use.
Smart temperature control for stable water
As the water shifts, the heater adjusts its output to reach and hold the set temperature. This adaptive heating helps minimize sudden temperature swings that can stress fish, turtles, and shrimp, while also avoiding unnecessary energy use.
