About this item
- Safe PTC Ceramic Heating Core – Fully ceramic, shatterproof and explosion-proof design. Unlike fragile quartz glass heaters, this 300W aquarium heater offers stable heating and enhanced safety for 100–300L freshwater tanks.
- Precise LED Temperature Control (18–35°C) – External digital thermostat displays real-time water and set temperature with ±0.5°C accuracy, maintaining a consistent environment for tropical fish, shrimp and turtles.
- Dry-Run & Overheat Protection – Auto shut-off when water level drops (E0 error) or when water exceeds the set temperature by 3°C. Protects fish and prevents equipment damage.
- Fast & Energy Efficient – PTC technology heats up to 20% faster and saves up to 30% energy compared to quartz glass heaters, ideal for keeping stable temperatures with less power usage.
- Suitable for Freshwater & Low-Salinity Tanks – Designed for freshwater aquariums and most low-salinity setups. Not intended for high-salinity marine tanks due to potential corrosion of the heating core.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
