### ⭐⭐⭐⭐ great
*by A***M on 5 December 2025*

These Zacro digital aquarium thermometers are a handy addition to my tank setup. They’re simple to install — stick one where it’s easy to read — and the LCD display gives a clear, accurate temperature reading that helps me keep water conditions stable for fish. Having two in a pack is useful for checking different areas (e.g. near the heater and a different spot in the tank) to ensure the temperature is uniform, which is especially helpful in larger or deeper tanks. The small size means they don’t take up much space and don’t interfere with décor or flow. The only minor downside: the adhesive occasionally loosens if there’s a lot of water movement, so I sometimes have to re‑stick them. Overall, though, they’re a reliable, inexpensive way to monitor tank temperature — a good buy for any fish keeper.
