Digital 300W

The AQQA Digital 300W submersible digital heater is a high-performance solution for temperature management in medium-to-large aquariums up to 280 liters. Built with an explosion-proof quartz glass tube and energy-efficient carbon fiber heating elements, this heater provides uniform and rapid heating. The dark ABS plastic guard acts as a physical barrier to keep active fish and invertebrates safe from contact burns.

The inline external LED controller simplifies temperature regulation, allowing adjustments from 15°C to 34°C (59°F to 93°F) outside the water. The smart safety system includes dual probes that instantly cut off power during dry-running (E1 code) or overheating (HH code) to avoid catastrophic failures. A built-in memory module automatically restores target settings when power is restored.
