Review on 🌡️ Fluval EDGE Digital Aquarium Thermometer: Measure Aquarium Temperature with Precision (64-86°F) by Betsy Tran

Easy to use, looks accurate, cheap. Perfect. I attached it to the outside corner of my little five gallon tank. The room that my fish tank is kept in is usually cold and as the winter season approaches I wanted to make sure I have an idea of if my fish tank is warm/cold. I bought a heater and this thermometer. I almost bought one to mount inside, but space is limited in this tiny tank. It's perfect. This thermometer is unobtrusive - I don't pay attention to it when I look at my aquarium. It is simply attached to the outside of the tank, so there are no problems with setting it up. Displays a temperature range that appears accurate. Thanks to this and the heater I added, my guppies seem a lot happier.
