Review on 🐠 Enhance Your Aquatic Environment with our Fish Tank Aquarium Heater - Flexible Submersible Thermostat Heater, 25W/50W/100W/150W/200W/300W by Tina Campanita

After receiving this 100 watt unit I put it in the aquarium. There are no fish yet, only plants. The water temp was about 72 and I wanted about 72. So I turned on the heater and waited a few hours. It still showed that it was still getting hot. I checked the water temperature and it was 76°. the heater is set to 72°, i turned it off and will buy another heater. He was bad from the start. Heck, I don't see myself getting another one of these blocks. I'm not sure if it's worth the hassle of sending it back.
