Review on 🐠 2-Pack CNZ EH-100W Submersible Heater for Aquarium Glass - 100W by Wendy Owens

Inexpensive and clean. What more can you ask for? I bought these heaters because they were really cheap and I didn't care how they looked aesthetically or what type of heating element they used. All that mattered to me was whether they maintained the exact temperature of the water. I used them in a 36 gallon tank for several months and they worked flawlessly. I am very comfortable. And yes, I know there is algae in my aquarium, it's time to clean it 😁
