Review on 🐠 Woliver Aquarium Heater: Dual LED External Temp Display, Submersible Fish Tank Heater (100W/300W/500W) - Ideal for Saltwater & Freshwater Fish by Debra Depts

The temperature was rising, so I decided to try this 100W. First, it was too long to fit in my aquarium. The top stuck out about an inch and touched the bottom of the tank. I liked how it has external temperature control and a reading area. It has an "actual water temperature" and a "set temperature" so you can see where your tank is. I felt like I had to set the temp a few degrees higher than I needed to get it to the desired temperature. I have a small filter and an air stone that circulates in the water and since it's a rather small tank I figured that would do. But it doesn't look like it. It was very difficult for me to maintain the integrity of the tank. But the nice thing is that there is an audible alarm that will go off if your tank is said to be too hot for fish. I've had this tank for several years now, so I have a hard time believing I did anything wrong. I'm just not a fat thermometer, it was very accurate, but I liked the design.
