Designed for Small Tanks: 150W mini aquarium heater provides stable heating for small 20–30 gallon freshwater or saltwater tanks, with an adjustable range of 59–93°F. Compact size (8.1″ × 1.06″) fits easily in betta, turtle, nano tanks without taking up space.
Overheat & Dry-Run Protection: Automatically stops heating when the target temperature is reached. Shuts off with warning “EE” “ER” if water temperature exceeds 97°F or if the heater is exposed to air, helping prevent overheating and dry burning.
Durable & Fish-Safe Construction: Explosion-proof quartz glass with silicon carbide helps prevent cracking, while insulated ends reduce the risk of burns for fish and aquatic pets.
Easy to Set & Monitor Temperature: Digital controller displays real-time water temperature. Simple button controls let you set and save your preferred temperature. Clear indicator lights show working status—red means heating, green means the heater is on standby.
Important Usage Tips: Fully submerge the heater before powering on and place it in an area with good water circulation. Always unplug and allow the heater to cool for 15 minutes before water changes or cleaning.
