Review on 🌡️ Zacro LCD Digital Aquarium Thermometer: Accurate Fish Tank & Terrarium Water Temperature Monitoring by Candy Malone

This is a small, handy digital thermometer for accurately measuring the temperature in your aquarium. I have mine in a 65 gallon community pool and it has helped me get the temperature right after getting a new Eheim heater that may or may not need calibrating to heat to the correct temperature. I have tested this Zacro with a glass thermometer that is used in a chemistry lab at my work and it has proven to be accurate. This is within 0.5 to 0.7 degrees of what I set the heater to, but this could be due to water movement from air pumps, filters etc and the proximity of the Zacro temp sensor to the actual heater. As long as I'm within the set temperature, I know I'm ready. The Zacro attaches to the glass surfaces of your tank with a suction cup, and the probe has its own suction cup that can slide up or down the probe wire, allowing you to suction the probe up or down in the tank, depending on your preference. I turn mine on to check the temperature regularly, then turn it off to save battery. Zacro himself is small and unobtrusive. Mine is side mounted and complemented by a traditional aquarium thermometer. Having been in the aquarium hobby for over 25 years I can say that this small and very inexpensive unit is essential to keeping the temperature where your fish need it. it must be for their own good. So go ahead and get one and you won't be disappointed.
