This fully submersible aquarium heater is suitable for 283–492L freshwater and saltwater tanks, with an adjustable temperature range of 15–34°C (59–93°F). It features an external LED digital controller for easy temperature monitoring and adjustment, a power-off memory function to retain settings after outages, and a child lock to prevent accidental changes. Built with explosion-proof quartz glass, a corrosion-resistant heating element, and a protective ABS outer shell, it provides safe, even heating and long-lasting durability. Multiple safety features, including dry-run protection, over-temperature protection, and an APS fault detection system, automatically shut off the heater and activate alarms if issues occur. An intelligent variable-frequency chip maintains a stable water temperature while reducing energy consumption by adjusting heating power as needed. The heater includes a heating rod, external controller, and two suction cups for flexible installation. Available in 200W, 300W, and 500W options to suit different aquarium sizes.

I made every effort in accurately describing the item (size colour, functionality).
Please note that I'm a private seller and not a power seller.
Generally I do not accept returns and on those rare occasions where I agree to a return, I expect the buyer to contribute to the return postage fee.
For some bulky items, I offer collection in person. If you're bidding on one of those items, please be sure that you are really able and willing to collect as I received many cancellation requests for "collection only" items in the past. Thank You!
