Review on 🐠 DaToo Aquarium Heater 50W: Mini Fish Tank Heater, 50 Watt Submersible with LED Temperature Display by Stacy Glasrud

The first one we received didn't work but was quickly replaced. The second works great. It's easy to set up and accurately maintains a constant temperature. It is small enough not to spoil the tank's decor. I'll get another one for my other tank. UPDATE: I bought another heater and it works great. I recommend these heaters to anyone with a 10 gallon tank. They make a great addition to any tank and are easy to read.
