Aquarium Thermometer - Digital Thermometer with Probe and Suction Cup, Reptile Fish Tank Thermometer with Large LCD Display, Terrarium Water Temperature Test

These have been an amazing purchase for my mixed reef tank.The battery lasts around 6 months and it is always very accurate and reliable.The sticky cup is good but I never really used it for sticking on as I left it beside my tank.Very easy to read from all angles. A highly recommend purchase for your tank.

Easy to stick onto the tank, simple to use, nice size display, accurate temperature recording. Well worth the money. Definitely recommend to anybody wanting to keep track on the temperature of their aquarium. Great for our tropical tank!

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.

Aqurate temperature monitoring, easy to see display, good quality and good suction cups. Comes with batteries. Prob going to the water and the monitor is outside the fish tank.

So far so good. Just set it up, it's been 30 minutes. Reading a similar temperature to the other side of the aquarium. Suction cups seem alright.

Works well, it is accurate. I have tested the accuracy by using a few different thermometers and this thermometer gave the most reliable and consistent reading. The suction for the probe sticks well to the tank. Battery life seems to be good. If this thermometer is placed well in the tank it can be hidden, lots spoiling the aesthetic of your tank.

This is a great product. I bought one of these for my other aquarium 1 year ago and it still works well. Decided to buy the same one for my new aquarium. The only thing I would say is that Amazon delivery driver flung it over the fence of a neighbour, far up the road. Luckily the neighbour found it and brought it round to me. The app said it had been delivered to our letterbox. Complete lie. Wrong house - mistakes happen. Flinging it over a random fence another matter.

Great little accurate thermometer but is very untidy wires to look at when installing no way to make it look good on the aquarium otherwise would get five stars but the look is very important

I've had these less than 12 hours but they seem to be working perfectly. I have a huge fish tank with Bettas outside the glass sliding door in the living room. We love to watch them at night, but with the cold weather we have been having here in South Florida I put some foam insulation on the tank to prevent heat loss on the sides, and back. The bottom, top and front were still exposed, so I got an electric blanket to cover the top and front to prevent heat loss, and I stuck an Aiicioo 24 watt 18 x 8 inch Under Tank Heater pad to the bottom. I wanted to raise the electric blanket off the front so that we could watch the Betta and his 7 newborn 'kids', but I was hesitant because I wasn't sure how fast the cold weather would pull away the heat. I also have two immersion heaters in the tank, but with such a large tank I had doubts as to their performance in this cold weather. I placed the probe of one of the thermometers all the way to the bottom and got about 62 degrees Fahrenheit. I then placed the probe of the second thermometer near the surface, just over 12 inches from the immersion heaters and got 89 degrees Fahrenheit. I found it strange that the temperature at the bottom was so low, so I checked the Lutron app on my phone and saw that the switch for the heating pad was off. That was around 1:00pm, so I turned the heating pad on and left it. Around 7:00pm when we came back from shopping I took this picture and the surface temperature had dropped to 87.9 degrees and the bottom temperature had risen to 72.2 degrees, and this is with the front exposed. This is exactly what I needed the thermometers for. Knowing that the temperature would continue to fall during the night, I turned the electric blanket on to prevent heat loss from the top of the tank. As you can see in the picture, papa Betta(I gave mama away because she was eating her hatch-lings) is sitting between the two immersion heaters, even though the surface temperature is at the higher limit of his comfort zone. Bettas tend to reside at the surface so I'm not too worried about the temperature at depth, nevertheless I'd like the bottom temperature to hit 76. The funny thing is that the babies don't seem to mind zipping around in the colder water at the bottom, but they tend to stick mostly from mid-level to surface. These thermometers will allow me to properly monitor the temperatures and only turn on the electric blanket when it is absolutely needed. It's true the thermometers don't have a back light, but light uses up a lot of power, and for the few seconds I'll be looking at the thermometers, I can use the light on my cell phone. Wonderful and simple product and I love that each one comes with two good suction pads. You can't complain at this price.

Small yet does the job. Easy to use. Been my companion in taking care of my flower horn, to make sure that I am giving and monitoring the correct aquarium water temperature. I think this could be useful also when checking water temp in the bucket before you give bath to your babies.
