Floating Glass Thermometer

Ended up not using it on my tank but it works perfectly fine

nice little thermometer

It's a nice little thermometer. It's great that it has the "green" range from 70 to 80 degrees as our tank is in my son's room and that means he doesn't even need to read the temp, he just needs to see if it's in the proper range.

Work great in the tanks keeps temp accurate for my babys.
