LLC 43330972: Liquid Crystal Aquarium Thermometer Vertical

Temps where I live has dipped into the 50's I left my sliding door open about 4 inches so my living room where my Oceanic BioCube sits got chilly. When I went to feed my fish I could see 68 on this gauge. I bought this gauge From a forum recommendation and I put this gauge on my 3 aquariums. Because of that I could visually see that the Cube's water temp had dropped. When I opened the door to my Cubes stand I saw that the Heater was unplugged. I unplugged it while doing a water change and then I forgot to plug it back in.when I was done. One of the best things I have done for my aquariums was to add this stick on temp as a visual backup, so I can better monitor my aquariums TEMP at a glance! This large stick on gauge (easy to see temp) saved me that morning. This weekend outside temps are supposed to be in the 30's so the water could have gotten even colder. This gauge IS my Visual Backup! It matches the temp on my Heater and internal glass thermometer so I trust it. So far so good month's later. If it changes it's reliability I will report back. I give it 2 thumbs up!

I really like the way this thermometer looks and works. Quickly adjusts to reflect the water temperature virtually immediately after it's applied to the tank. My favorite feature is that it's very easy to read. This is because not only are the size of the individual temperature indicator blocks and the brightness of the associated background colors perfect, but the numbers representing the temperature are crisp, black, and appear right inside the color blocks. Visually striking and extremely easy to read. And it's moveable! Good aquarium thermometer at a reasonable price point.

Great visibility. Accurate. Moveable!!! it being movable is wonderful. Typically they’re destroyed when you try to move them. This is an excellent product.

Pretty much a basic thermometer, it’s accurate but it goes based off every 2 degrees. Not to mention you can remove it multiple times if you don’t like where you put it. They only drawback is that you can’t see the temperature from far away, you really need to stand up close to it. Other than that it works perfectly fine and it’s caused no problems. Definitely recommend this for any aquarium, thought not saltwater.

So yeah, as far as stick on thermometers, this is the best one I've used thus far. It sticks well, resists saltwater drips on it, and has very bright and clear numbers. Through 5mm glass it's temps match what my heater is saying.

Works perfectly!

I needed a thermometer for my 40-gal fish tank and didnt want it to be in the way. This stick-on thermometer is great for sticking on the outside of your fish tanks unseen and will keep the correct temp at all times. I do keep a small flashlight handy to shine on it since it reflects off light to see the numbers. Very important if you want your fish to survive

Placed on my Marineland Portrait 5-gallon aquarium. It displays the temperature bright enough to read without a problem and is accurate. It was easy to install. It's just the right size for a small aquarium. Once you learn what the colors mean it's easy to tell exactly what temperature the water is within 1-degree Fahrenheit.
