Boxtech Submersible Aquarium Heater 300W for 55-80 Gallon

Product Review (submitted on February 23, 2022):

Sits horizontal near the bottom of my tank behind plants underneath a filter intake.

House temperature is dropping into the 50s at night and this heater has had no issue keeping the tank at a steady 76 degrees.

It looks nice with the cage and its really useful having the temperature controller actually outside the water unlike a lot of other units. Great price, great product.
