Review on 🐠 110V Aquarium Water Chiller Cooler Warmer with Pump - 50 to 104°F Temperature Setting - Suitable for 60L/16Gal Water - Ideal for Home Aquarium Fish, Shrimp, Coral, Jellyfish - 200-300 L/H by Lisa Norman

Purchased to lower the water temperature in my aquarium. Overall very happy with the design of the cooler, it is very well made, solid and easy to install and set up. But when testing the water coming out of the aquarium and the water leaving the cooler, the temperature difference was only 1-2 degrees. It is unforgettable that the efficiency of the chiller depends on the temperature in the room. According to my testing, if you have a 75-degree room, if the cooler lowers the water temperature by one degree, you're lucky. So, with a water temperature in the aquarium of 80 degrees, you can see the temperature of the water leaving 79-78 degrees. After a week of operation, the cooler was still unable to bring the aquarium water to room temperature. To keep tropical or saltwater aquariums at the right temperature, it's not worth buying this cooler unless you plan on keeping the cooler in a very cold environment.
