About this item
- Upgraded 500W PTC Ceramic Heater – Safer, shatterproof alternative to traditional quartz heaters. Perfect for 250–500L tanks, delivering consistent heat output without risk of cracking.
- Smart External LED Controller – Shows both current and target temperatures in real time with ±0.5°C accuracy. External design keeps hands dry and settings accessible outside the tank.
- Advanced Safety Features – Dry-run sensor shuts off when exposed; over-temp cut-off activates 3°C above setpoint; automatic thermal regulation prevents overheating.
- Rapid & Efficient Heating – Achieves target temperature 20% faster while reducing power consumption by up to 30% versus standard aquarium heaters, keeping large tanks energy efficient.
- Freshwater & Low-Salinity Compatible – Optimised for freshwater aquariums. Suitable for most low-salinity tanks but not recommended for high-salinity marine use due to core corrosion risk.

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.
