"These are great!"

So, in those cases, I find it easier to simply replace it. I was using one of those ubiquitous cheap digital thermometers on Amazon. Ambient room temperature measures 72. I guess these units do not like saltwater. The extra batteries where very much appreciated and came in handy. I have it in both my aquariums now.

89 I could buy Six Thermometers with Six included batteries. I was using one of those ubiquitous cheap digital thermometers on Amazon.

"Or left a mark."

This is how you calibrate a thermometer. I find that the temps are accurate, and this product gives added peace of mind. 2 deg, if it was 32, it would be a SOLID block of ice. If the digital display starts to get dim, it's time for a new battery. All were Close enough for a fish tank and other uses. I used these to raise chicks, and in my parrot cages. 89 I could buy Six Thermometers with Six included batteries.

"2 deg of 32."

Sure enough the digital thermometer was way off by 6 degrees! I guess these units do not like saltwater. So much so that I purchased a second set of 6. I have kept aquariums for about 45 years. It's kind of difficult to hide and keep out of the way. I needed a solution that was not breakable and these do the trick! The lid is textured aluminum, and the suction cups don't stick to that.

  • Vipe Aquarium Thermometer Sticker Fast-Read Thermometer Stick On Aquarium Fish Tank Glass Greenhouse (1pcs)
  • Monitor tank temperature --- Keep fishes, shrimps, reptiles & turtles comfortable by making sure the water isn’t too hot or too cold. Irregular water temperatures can cause fish to be stressed or sick and develop white spots.

  • Clean, practical design --- Measurement range: Fahrenheit degree 64-93°F or Celsius degree 18-34°C. This all black thermometer changes color according to the temperature. If the water temperature is 80°F, the background scale of 80°F will turn into blue color to indicate your reading.

You can glue, tape or simply cover the cords in the tank to keep them discreet. I used these on a number of my aquariums that have discus fish in them. I bought these for my dwc reservoirs. In this scenario it would probably get knocked loose a lot. And I just really started to doubt it. I recommend gluing the suction cups in place where needed for long-term installation.
