CONGGUAN 4Pcs Aquarium Temperature Meter Sticker Thermometer Strip Tank Fish Thermometer Temperature Sticker for Home Fish Tank and Aquarium Measurement 18-34°C

These work perfectly, easy to read and stuck to our tank just fine. Good value too with getting 4 in a pack

Great for tanks

The CONGGUAN Aquarium Temperature Meter Stickers offers a simple, efficient way to measure the temperature of your fish tank, DIY brewing setups, or pet tanks. The self-adhesive design allows for easy application, just peel and stick it onto the surface of your tank or container. The thermometer features colour-coded bands that make it easy to quickly check the water temperature, ranging from 18°C to 34°C. With a pack of four pieces, it's a practical option for multiple tanks or setups.One potential drawback of this product is that once applied, the stickers are extremely sticky and can be very difficult to remove without damaging the surface. This makes them a bit more challenging to reposition if needed. However, if you're looking for an affordable and convenient solution to monitor your aquarium's temperature, this thermometer strip is a solid choice for low-maintenance monitoring.

Very cheap and effective helping me monitor temperatures in my scorpions enclosure.

1 out of the 4 actually works but temp is totally out. Don’t waste time and money getting these. Getting them off is also a problem leaves sticky stuff on tank which is almost impossible to remove

Temperature isn’t that clear the colours are not very bright but cheap and easy to stick on

Good

It can be cut. I cut it because it's longer than the aquarium is tall and it works. And I wash the entire aquarium every week with hot water, but it stays stuck.
