Marina Deluxe Floating Thermometer w/Suction Cup

The Marina Deluxe Floating Thermometer keeps a clear eye on your water temperature with a weighted glass thermometer that stands upright in the tank and a suction cup that holds it right where you want it. A color-coded safety zone shows at a glance whether your water sits in the comfortable range for tropical fish, and it is safe for both freshwater and saltwater aquariums. Pair it with a reliable aquarium heater to hold your water in the right range.

Features

• Deluxe floating glass thermometer with a weighted base that stands upright
• Suction cup holds it in place at the height you choose
• Easy-to-read dual Fahrenheit and Celsius scale
• Color-coded safety zone indicator for tropical fish
• Helps protect your fish from unsafe temperatures

How to Use

Wet the suction cup and press it against the inside of the aquarium glass, or let the thermometer float upright on its weighted base. Position it away from the heater so you read the true tank temperature rather than the warm water right at the element, give it a minute to settle, then check the reading against the safety zone.

FAQ

Does it work in saltwater?
Yes. The floating thermometer and suction cup are safe for both freshwater and marine aquariums.

How is it different from the plastic thermometer?
The deluxe floating model stands upright on a weighted base and can float freely or mount with the suction cup, while the flat plastic model sits directly against the glass.

What is the safety zone?
A color-coded band on the scale that shows the comfortable temperature range for most tropical fish, so problems are easy to spot at a glance.
