These aquarium thermometers are mercury free, and are designed
for a quick, easy, and reliable temperature readings.
They’re safe to use inside both freshwater and saltwater fish tanks.
Optional Suction Cup:
Each Floating Aquarium Thermometer comes with an optional suction cup,
which allows you to place it alongside the tank’s walls for even easier access for a temperature reading.
The suction cup mount is removeable, and the thermometer should float on its own.
Please Note:
Please place the thermometer vertically inside your fish tank.
This allows the colored liquid to pool at the bottom, and give an accurate temperature reading.
Some settling may have occurred during the delivery process, but the interior liquid
will return to the bulb once it’s set into a vertical position.
Measurements:
Overall = 0.5” (W) x 0.8” (D) x 4.25” (H)
Suction Cup = 0.8” (Dia)

Here is an inexpensive thermometer for aquariums. It is accurate and easy to use. The suction cup application works well and the numbers are easy to read. I have had other thermometers but still go back to the simplest and most inexpensive as the best.

Works. There are a lot of fancy thermometers out there, this one is just simple old school reliable. I was getting frustrated with every digital thermometer giving me different reading, so I went back to basics. Glad I did, it works well.

It was a waste of money and a very big dissapointment since it arrived shattered and I couldnt return it because Amazon said it was a non returnable item, even though it arrived broken.I was suprised when I opened the box as soon as it arrived and it was shattered in pieces.I would have been very afraid to put it in my betta fish tank even if it would have been intact because of its paper thin glass that could so easily break in my hand just by putting in the tank.Dangerous for me and my betta fish.I never sent a bad review on anything before but this I feel I need to warn anyone who's thinking of buying this cheap thin and dangerous aquarium thermometer.

I love having this in my bettas tank and I check it easily all the time. It makes me feel safe to know my fish is in the right temperature range where he is thriving and happy. Thank you!

Works well so far. Suction cup is strong and far better then my last thermometer! Sitting comfortably in the green zone for my fish.Arrived at below 0°c on my doorstep and is now 23°c, so I know it's working perfectly.
