🌡️ Marina Aquarius Thermometer: Fahrenheit 72-86 Degrees Review

Nothing to say, it does what it's supposed to do and it's nice and small for smaller aquariums. Exactly as far as I can tell.

Not very accurate, sometimes shows 3 bars so I'm guessing what the temp really is. Also, it's the smallest sticky thermometer I could find, so it's perfect for my nano aquarium.

I have excellent eyesight and am not color blind. However, looking at this thermometer makes me feel like I suffer from both. Basically unsuitable. The ATI thermometer works well and is visible.

This thermometer stays black even after a few hours (see my customer's picture). The tank heater is set at 82°F for my Betta and I wanted to make sure the heater was working accurately. I like the small design but this thermometer is useless.

I got this thermometer for my first 10 gallon tropical aquarium. It works well to see if the temperature is in the right range (74-82), but not well when you need accurate readings. A square is approximately 3 degrees, and typically 3 squares will light up (the middle one is the brightest).
